introduction
The SATRA, spol. s r.o. offers complex design, consulting, engineering and architectonic services, from investment projects
to approval and evaluation of trial operation of civil, industrial
and engineering structures. For more than 20 years, our opinion is that high-quality work always requires perfect technical
equipment, skilled professionals with extensive theoretical
knowledge, who are interested in their relevant specialization,
and adequate working environment.
We fulfill the basic vision of our Company every day: our work
target is a high-quality result. Our initiative and effort is focused
on this target for the whole time of its realization. Therefore,
when realizing our orders, we make an effort to ensure active
approach, above the framework of our contractual obligations.
We always provide the most complex services possible, with
emphasis on high quality level. Every order, regardless of its
scope or attractiveness, represents for us something more than
a business case only; we perceive our work as an obligation necessary for successful completion of the relevant construction.
We are convinced that only the quality of the services provided, without any attributes, will satisfy our business partners
and customers. Therefore, we apply a process control method
when we evaluate continuously efficiency of all processes, in
particular the control processes. After all, it is always our work
that speaks for us and that is our credit. It is always complex
work, from the order acceptance to putting the entire construction into operation. Consistent monitoring of every detail
and effort to offer our clients maximum quality and precise
services – this was, is and will be our specific feature.
We are the users of our constructions, therefore every detail
is important to us. We are looking for environment-friendly
solutions that serve their purpose efficiently. Our work helps
creating the world in which we live.
However, we are not designers and consultants only; research
and publishing activities are an indispensable part of our work.
We publish specialized books, we contribute to well-known
professional periodicals, and we produce audio-visual works
and operate internet portals. We are engaged in research in
the area of building structures and technologies, fire ventilation or traffic safety in vehicular tunnels. We are active members
of several national and international professional associations.
You are holding in your hand the profile of our Company with
more than two decades of successful existence. Within this
time period, we have worked for several tens of clients. We
have brought to life hundreds of various projects. It is impossible to list all of them, neither is it possible to specify completely all the services offered. Our ambition is to introduce the
best of our work within the past twenty years of which we can
be rightfully proud.

Monitoring of structures
and survey of structures
The so-called monitoring is not only an integral part of
constructions realized by the mining method (e.g. driven
tunnels), but now also of many other extensive constructions
which influence their surroundings. The monitoring consists of
measuring and monitoring the construction realized proper,
and also of structures and their surroundings influenced
by the construction and building activities. In particular, it
concerns impacts caused by the terrain lowering, changed
hydro geologic conditions, seismic effects from blasting works
and building machinery, etc. In particular, deformations,
inclinations, drop faults, deformations occurrence and
development or also noise loading.
The monitoring must also include survey of passports of
the monitored structures in order to determine their real
condition before and after the construction realization. This is
the only way how to prevent potential property right disputes.
Survey of structure, in other words documenting of the as-is
condition of a structure, is also used in other situations than
in case of impacts caused by building works. It is also a part of
the contractual relation concerning lease or sale of a structure,
for the needs of reconstructions, etc.
8
Owing to our working team´s experience, we provide complex
services in the area of monitoring and survey of structure of
buildings. We ensure the entire process, from the solution draft,
the measuring and monitoring deliveries proper, including the
survey of structure compilation, to final evaluation of repair
plans till completion of the whole construction.
Also in this area our specialists apply their experience,
obtained from active participation in research projects in the
area of building structures or tunnel linings monitoring and
evaluation.

THE COMPANY HISTORY
The SATRA Company has arisen from the sixth atelier of the
Military Design Institute in Prague in the year 1991. Regarding
continuity of the original specialization of individual
employees, emphasis has been put on constructions with
high technology ratio and on underground structures. Within
its more than twenty-year-old history, the SATRA Company
has realized orders for major domestic and foreign investors,
in particular for the state administration and urban selfgovernment authorities. In the long run, the most important
clients are the Capital of Prague and the Czech Republic
Ministry of Defense.
The Company participates significantly in preparation and
realization of the Prague superior road system. It acted as
the coordinator of the construction and technologic part
at completion and gradual putting into operation of the
Strahovský vehicular tunnel, then as the designer of the
driven parts and technologic equipment of the Mrázovka
tunnels. At the present time, it is the coordinator of the design

MRÁZOVKA TUNNELS
The Mrázovka tunnels are a part of the Urban Ring in the
territory of the fifth Prague district. They consist of two threeline tunnels which split in forks into two-line tunnels in the
Urban Ring route and into single-line branches in the Radlická
street. The tunnels driveage proceeded in complicated
geologic conditions, in shallow depths under the Smíchov
development. Within the driveage course, the so-called
observation method has been applied in the Czech Republic
for the first time, including a monitoring system, designed by
the SATRA Company. Knowledge obtained from the Study
of the tunnel structures operation safety, elaborated by our
Company in the year 2003, has been implemented in the final
design of the tunnel interior. The Mrázovka tunnels represent
a high safety standard according to the all-European standard
also owing to the above concept. The construction has
resulted in significant improvement of the traffic and emission
situation in the entire Smíchov territory.

construction of six new bridges was also a part of optimization
of the 2nd and 3rd railway corridor between Zábřeh na Moravě
and Krasíkov. Rectification of the railroad track was necessary
in order to allow the railway speed increase to 160 km/h. The
order was financed within the ISPA program. The general
technical and financial management of the construction
proceeded in compliance with the EU regulations and with the
FIDIC contractual conditions. The SATRA Company supervised
the tunnel sections. The supervision goal was to make sure
that the construction works are realized within the Design
Documentation scope, within the time period specified,
within the approved investment costs and in compliance with
the technical parameters specified in the Contract.

Construction
of the Blanka
tunnel in Letná
(Prague)
BLANKA TUNNEL COMPLEX
The Blanka tunnel complex is divided into four separate
constructions, the design preparation of which has always
proceeded simultaneously and was therefore coordinated so
that the entire complex of constructions were one functional
whole. The route passes under urbanized environment on
the boundaries of the historical Prague center; it is routed in
driven and cut-and-cover tunnels, with connection ramps
in important junctions. It is one of the most complicated
constructions that have ever existed in Prague, not only with
regard to the transportation structure proper, but alsodue
to the number of necessary relocations of buried services
or traffic measures during the construction. Such demands
scope is comparable probably with the first operating subway
sections only. The total length of the tunnel complex is 5,5 km,
from that the driven sections measure almost 3 kilometers.
The ventilation machine room under Letná represents one of
the biggest driven spaces in the Czech Republic.

The Lednicko-Valtická area belongs among the largest parks
in Europe that have ever been completed by human hand. In
the year 1992 it has been declared a protected landscape area
and in December 1996 it has been registered in the UNESCO
List of World Cultural and Natural Heritage. It also includes the
Valtice castle complex. The order subject is renovation and
reconstruction of the original baroque theatre in the castle
complex so that it would become a part of the National Theater
and dance center. The theatre building forms a separate wing,
jutting perpendicularly in the south-east direction from
the castle corner and from the castle moat to the park. The
building will be utilized according to its original purpose as
a baroque castle theater for 240 spectators and 60 actors. The
theater proper will be located in the original theatre wing; the
background for guests and actors will reach into the adjacent
castle areas and into the former pressing shop interior.

The Příkopy
Collector (Prague)
PRAGUE COLLECTORS
Construction of collectors for routing of pipe and cable buried
services in the Prague center, in the section of Václavské square
– Obecní dům. When routed in the collectors, the buried
services are accessible for continuous inspections, repairs
and maintenance. Potential defects are removed directly in
the collectors, without roads disturbance, i.e. without any
traffic restrictions. The driven collectors are being constructed
directly under the historical built-up area. The Prague
collectors under the historical center of the City are not only
a functional structure, but also a phenomenon that attracts
professionals and well as lay enthusiasts. The collector section
Centrum and Příkopy is a part of an attractive sightseeing
route for the public.

traffic reduction
(Prague)
REDUCTION OF THE NORTHSOUTH
ARTERIAL ROAD TRAFFIC
At the present time, the North-South arterial road is one
of the busiest highways of the Capital of Prague, with all
its negative and positive aspects of such a transportation
structure which influence the City life. The situation is the
more serious because the arterial road is routed crosswise the
City center proper and it reaches the margin of the UNESCOprotected Prague monument reserve. Within the past years,
its section at the national Museum – however, not only here
– has become one of the most problematic traffic locations in
the very heart of Prague. In its entire length, the arterial road
degrades significantly the urban surroundings, worsens its
habitableness as well as the recreational potential of adjacent
park areas and degrades the urban significance. The City life
and the urban functions in its vicinity stagnate in fact. The
studies target was to design such solutions that would be in
compliance with the conditions of permanently sustainable
Capital development, improve the environmental conditions
not only in the inside area of the Urban Ring, allow new
urbanistic incorporation of this highway into the City, remove
the urbanistic an space barriers and allow rehabilitation of the
non-urban areas and unsuitable solutions in the arterial road
neighborhood.

Archive and the MHMP Administration Archive in an ideal
operational sequence to the existing building that has been
completed structurally in the year 1997. It means construction
of a new operational – deposit building, extension of the
conference hall in the existing entrance and administration
building and the energy-center reconstruction. The building is
located at the south façade of the existing service building to
which it connects by an interconnecting communication link
on the level of all the floors. Regarding its mass, it is identical
with the existing deposit building; one underground and
six aboveground floors are realized in the first stage of the
construction. The bearing elements of the building and of the
foundation structures have been designed and realized so
that they would allow the building extension to the final 12
aboveground floors in the future.

RESEARCH
The SATRA Company participates in research projects in the area
of fire ventilation and of vehicular tunnels safety, in measuring
of stress and evaluation of engineering structures condition.
on methodologies of vehicular tunnels risks assessment in
individual Member States and advocacy of the Czech Republic
interests in the Committee in compliance with the approved
transportation concept in the ČR.
Smoke spreading at fire in a road tunnel
A project from the area of computer modeling regarding
vehicular tunnels ventilation in case of a fire, with application of
the CFD – Computational Fluid Dynamics program, applied to
the Prague Urban Ring. The issue has been researched with the
application of the Euler-Lagrange´s CFD model. The modeled
tunnel geometry corresponds to the road tunnel Myslbekova –
Pelc-Tyrolka that is a part of the Prague Urban Ring.
Risks in vehicular tunnels
The Project should ensure fulfillment of requirements at
creation and implementation of the European methodology
for the Czech Republic vehicular tunnels safety and risks
assessment. The Project content and goals take into
consideration the requirements of the European Parliament
and Committee Directive 2004/54/ES, On minimum safety
requirements on tunnels on main surface routes; it imposes
several tasks on the operators and on the EU member states.
In particular, the Project should allow fulfillment of the above
obligations, ensure compliance of Czech standards and of the
European methodology that is being created and preparation
of suitable conditions for timely introduction of the European
risks assessment methodology in the Czech Republic.
Activities in the Vehicular Tunnels Safety Committee
The Directive 2004/54/EC, dated April 29, 2004, specifies the
minimum safety requirements on tunnels of the trans-European
vehicular network. Based on a mandatory contract with the
ČR Ministry of Transportation, the SATRA Company managing
director and general manager, D. I. Ludvík Šajtar, is the Czech
Republic representative in the Vehicular Tunnels Safety
Committee within the Committee for Power and Transportation
of the European Commission. Besides other, it includes ČR
representation at the Committee sessions, preparation of reports
concerning the condition of the Directive implementation in the
Czech Rule of Court, elaboration of reports concerning situation
in the Czech Republic for the EC committee, preparation of
reports on experience with the Directive implementation and

Experimental verification of tunnel linings effect
The number of tunnels under construction and tunnels which
will be constructed in the furure keeps on increasing. Their
importance is essential for road and railway transport and it
is impossible to allow unnecessary traffic closures or other
traffic restrictions. Designing of the final tunnels lining is
a comparatively complicated process. The static effect depends
on the tunnel lining interaction with the rock massif and the
loading depends on many factors: the lining rigidity, stope
size, geotechnical conditions, construction progress and last
but not least, on climatic conditions. The structure evaluated is
often statically indefinite and it is impossible to apply directly
the designing methods according to the limit values in a form
that is standard in case of surface structures. Therefore, the
lining design must be safe, economical and simultaneously, it
must fulfill the highest requirements on utility characteristics
for the entire lifetime of the Work. Experience with longterm functions and real stress vary all over the world and it is
essential to verify the relevant experience in Czech conditions.
Innovation of evaluation methods of the existing engineering
structures
The main goals of the Project focused on the Prague region
include elaboration, implementation of and making available the
methodological principles of the existing structures reliability
assessment, with focus on concrete and walled structures (e.g.
panel and historical buildings). The methodology investigated
includes a part that is not covered in the European regulations
being introduced – evaluation of the construction condition
and of its residual lifetime, with the goal to optimize its renewal
plan. The methodology includes specification of resistance
models and of loading effects, using statistic methods, reliability
evaluation by the partial coefficient method and analysis of
economical and social risks. The general principles specified in
the new standard ISO 13822, Evaluation of existing structures
and in the up-till-now applied ČSN standards are being analyzed.
Emphasis is put also on economical evaluation of securing the
structures that are impacted by building activities (realization of
surface structures).

Od července 2010 se realizuje také
výstavba nového sdruženého mostu přes Vltavu mezi Holešovicemi
a Trojou, kde bude stavba ústit
do křižovatky Troja na Městském
okruhu. Most bude po svém dokončení nejširší v Praze a bude sloužit
pro vedení 2 x 2 jízdních pruhů pro
automobilovou dopravu. Doplní
je stezky pro cyklisty, chodníky
a především střední tramvajové
těleso. Po převedení dopravy na

Nejprve byly zahájeny práce na
stavbě 0079, byly hloubeny stavební jámy Troja a Letná. Z trojské strany byla v září 2007 zahájena ražba
2,2 km dlouhého raženého úseku,
zahrnujícího také ražené technologické centrum včetně rozsáhlé strojovny vzduchotechniky. V červenci
2009 začala protiražba z Letné; v té
době již probíhaly také práce na staveništích Hradčanská, Prašný most
a Myslbekova, odkud byla v říjnu
2009 zahájena ražba druhého
raženého úseku. V dubnu 2005 započala v předstihu výstavba MÚK
Malovanka, včetně portálového
objektu tunelu.
V prostorově a dopravně velmi
exponovaném území mezi tramvajovou smyčkou Špejchar a křižovatkou Prašný most se hloubené
tunely budovaly tzv. modifikovanou
milánskou metodou. Po vytěžení
mělké jámy byly vybudovány podzemní konstrukční stěny a stropní
deska, nad níž byly obnoveny
■
inženýrské sítě, byl upraven povrch
a následně obnoven provoz. Pod
V Obr. 1. Situace tunelu Blanka v severozápadní části Městského okruhu
ochranou stropní desky byl pak čelně vytěžen profil tunelu a byla vybudována spodní rozpěrná deska.
Obdobným způsobem se budovaly
i tunely v prostoru Patočkovy ulice
Značná část konstrukce tunelu
je umístěna do stavební jámy
hloubené z povrchu. Vzhledem
k nebývalému rozsahu odkryvu
(místy více než 25 metrů) tak stavba
tunelu představovala jedinečnou
příležitost pro archeology – mohli
zachytit stopy osídlení sahající až
do starší doby kamenné. Od října
2008 se při výstavbě prováděl
záchranný archeologický průzkum,
vedený Archeologickým ústavem
AV ČR v Praze a firmami Archaia
a Prospecto. Byla učiněna řada
významných nálezů, z nichž ten
nejdůležitější až v dubnu 2011. Severně od ulice U Prašného mostu
a barokního bastionu XIV. bylo
objeveno dosud neznámé pohřebiště, celkem bylo prozkoumáno
77 kostrových hrobů se 78 nebožtíky, z nichž nejméně 29 patřilo
dětem včetně kojenců. Na základě
nálezů šperků a keramiky je možné
toto pohřebiště datovat do sklonku
9. století až první poloviny 10. století.
Svůj otisk v krajině severně od
Pražského hradu zanechalo i období novověké. Stavba tunelu
Blanka ve staveništích Prašný most
a Myslbekova se bezprostředně
dotýká severního pásma barokního
opevnění Prahy. V rámci výstavby
se revitalizuje prostor pod bastiony
a vytvářejí se v dříve nepřístupných
lokalitách nové parkové plochy pro
veřejnost.
Křižovatka Malovanka
V současné době je téměř dokončena, pouze doprava je vedena
v některých směrech odlišně od
výsledného stavu. Hloubené tunely pod Patočkovou ulicí jsou ve
stadiu hrubé stavby, na stropě
tunelu budovaného v podzemních
konstrukčních stěnách je obnoven
provoz od Břevnova až ke křižovatce s Myslbekovou ulicí.
Staveniště Patočkova
Navazující úseky klenbových hloubených tunelů ve staveništi Patočkova jsou ve stadiu hrubé stavby
(obr. 1), téměř dokončeny jsou až
k objektu technologického centra TGC1. Probíhají hydroizolace
konstrukcí, zásyp stavební jámy
a jeho hutnění po vrstvách. Staví
se centrum TGC1 ve 4. úrovni nad
komunikacemi (obr. 2). Dokončen
je také vzduchotechnický kanál
a šachta, propojující centrum TGC1
s výdechovým objektem v ulici Nad
Octárnou. V ražených tunelech
Brusnice je hotové definitivní ostění. Pokládají se odvodňovací prvky
a obrubníky, ukládají chráničky
a betonují se chodníky v tunelech.
Staveniště Prašný most
Na tomto staveništi jsou v celém
rozsahu dokončeny hloubené tunely a vjezdová rampa 4 ze Svatovítské ulice. Staví se podzemní
garáže nad tunely, technologické
centrum TGC2 a výjezdová rampa 3
do křižovatky Prašný most (obr. 3).
V ulici Milady Horákové jsou provedeny zásypy na stropě tunelu
a připravuje se obnova komunikace.
V rámci výstavby Městského okruhu byl také snesen původní most
přes železniční trať Praha – Kladno
ve Svatovítské ulici. Nahradil jej nový
most v šířce celé komunikace, propojující Dejvice s křižovatkou Prašný most. Most je v současné době
stavebně dokončen, doprava je
vedena provizorně po jeho východní třetině. Je připravena definitivní
tramvajová trať na mostovce a na
severním předpolí mostu (obr. 4).
Západní zábradlí mostu včetně pylonů získá povrchovou úpravu podle
požadavků památkářů; východní
zábradlí mostu se vybuduje až po
převedení dopravy na mostě do
definitivního uspořádání. Zajíma-

Silniční tunely jsou vybavovány větracím systémem ze dvou
základních důvodů:
62
Q při všech dopravních stavech musí zabránit akumulaci výfukových
zplodin v prostoru tunelu;
Q musí zabránit šíření tepla, kouře a výparů při požáru nebo jiných
mimořádných událostech, osobám v tunelu pak musí během této
události zajistit cestu do bezpečí bez kouře a výparů.
Pro dosažení těchto cílů existují dvě základní koncepce větrání:
Q podélné větrání, kdy je proudění vzduchu v tunelu zajištěno podélně s osou tunelu;
Q příčné větrání, kdy je čerstvý vzduch přiváděn zvláštním kanálem
vedeným paralelně s tunelem a je zaústěn po určitých vzdálenostech do tunelu. Vzduch provětrává tunel příčně k ose tunelu a je
odváděn do paralelního odvodního kanálu.
O výběru systému větrání rozhoduje řada dalších okolností:
Q zda se jedná o tunel jednosměrný, nebo obousměrný; městský,
nebo dálniční; bez sklonu, nebo s velkým podélným sklonem;
Q předpokládaná intenzita provozu, podíl těžkých nákladních vozidel
z celkového počtu, výskyt dopravní kongesce, doprava nebezpečných nákladů tunelem;
Q místní požadavky na životní prostředí, které určují, zda je možné
vypouštět znečištěný vzduch přímo z portálu, nebo ne;
Q zvláštní požadavky provozovatele nebo jiných dotčených orgánů;
Q místní meteorologické podmínky (vítr, teplota, tlak na portály tunelu);
Q výběr větracího systému ovlivňuje řadu dalších aspektů souvisejících úzce s projektem tunelu (strojovny, výdechy pro přívod
a odvod vzduchu na povrchu, příčný řez, únikové cesty, elektrický
příkon silového napájení).

In an
underground
structure, a man
can be almost
imperceptible. The
mined ventilation
machine room is
one of the biggest
mined works
in the Czech
Republic. Only
a group of people
lends the structure
its real human
dimension.
