Strengthening of reinforced columns confining by modern composite materials is effective method, allows quickly realized strengthening, without increase dimension of strengthening columns. Just like using reinforcing bars, is the mainly assumption for this method the multi-axis state tension and deducing confining pressure, which will increase strength of concrete. Improved of properties of confining concrete can be determined by using relationships, but there are considerably differences. This diploma theses, dealing with strengthening of circular reinforced columns confinement by external FRP fabric, compared approaches to design of reinforced concrete by confining and using the results of an analytical and numerical study to describe problem of confining concrete and compare factors influencing the final properties of the wrapped concrete.

The subject of this diploma thesis is the design of deep foundation highway bridge on D3 motorway in km 112.574, over Bošilecký stream and evaluation of geomorphological, geological and hydrogeological conditions and perform static calculation bridge foundation

My thesis is focused on process preparation and building construction technology of primary lining road tunnel, implemented in city part of Troja in the capital city Prague. Specifically it is a part of tunnel complex Blanka. The name of this part is Kralovská obora. If the all tunnel parts are built this tunnel complex Blanka can be complemented to already opened tunnels Zlíchovský, Mrázovka and Strahovský which are the part of city traffic circle. This technology preparation includes schedules and financial plans of the building, technological prescription for the primary tunnel lining, safety plan, control and trial/test plans, environmental plan, project of construction site, design of the main working machines, items budget of the north tunnel tube, coordination situation plan with wider relationships transport routes and technical report of building technological project.
