The article deals with the geotechnical design and assessment of the foundation of a statically difficult bridge structure founded in complicated engineering geological conditions. Bridge structure No. 223 is part of the D3 motorway situated above the Hricov reservoir near the town of Zilina (Slovakia). The realized engineering geological survey showed that the geological composition of the subsoil is nonhomogeneous and complicated (occurrence of Quaternary soils and Mesozoic rocks). The physical and mechanical pr...

The paper analyses in detail size of vertical deformation (settlement) for various loading states that may occur during construction and operation of Hydropower Plant (HPP) in Gabcikovo. During construction and operation of the HPP complicated loading states were applied onto sealing elements of underground tank and subsoil of the HPP foundation. Geotechnical calculations, a total of fourth load states modelled, taking into account significant changes in the stress state and deformation in the subsoil and on the s...

In the article is analyzed the influence of relative stiffness and bonding of the "foundation -subsoil" interaction system on the value and distribution of the vertical normal and shearcontact stresses. The analysis of the calculated deformations of the foundation focused onthe qualitative and quantitative evaluation of the non-uniform settlement, respectively therelative deflection and flexibility of the foundation. In terms of relative stiffness areanalyzed the shallow square foundations from the "perfect rigid?...

The paper analyzes the vertical and horizontal deformations of the rockfill dam body of the pump-station hydropower plant (PHP). We are dealing in more details with geotechnical design and assessment of the reservoir lower dam. We concentrate especially to the results of mathematical modelling of the lower dam body and the asphaltic concrete sealing (both the vertical and inclined) as well as to possibilities of undemanding effect elimination. At the problem solution there was used numerical method of finite eleme...

The article dealing with optimizing of the foundation method a statically complicated bridge structure founded in difficult engineering-geological conditions. The Finite Element Method (FEM) was used to optimize the foundation method. Its mathematical apparatus makes it possible to take into account and define very complex and difficult boundary conditions of the solved engineering problem (material, geometric, static, etc.). The analysed bridge over the Danube River is located in Dunaujvaros (Hungary), which is a...

The paper deals with geotechnical design and assessment of pile foundations of the steel arch bridge structure, which was built on the motorway D1 in the Jablonov ? Studenec locality in Slovakia. Bridge structure is founded in a very difficult foundation conditions created by flysch rock environment. The bridge structure is statically difficult. Therefore, it was necessary to proceed in accordance with the rules applicable to the 3rd Geotechnical category when designing and assessing the bridge structure. The resu...

The article deals with the geotechnical calculations of the interaction of reinforced concrete storage boxes with subsoil at different loading states. From the numerical method point of view, this problem is solved by deformation variant of the finite element method. Defined the load states take into account the gradual filling of storage boxes with low and intermediate radioactive waste and final coverage of the storage boxes. More detailed are analyzed the results of the numerical calculations of vertical displa...

The article deals with numerical analysis of vertical normal contact stress in subsoil of foundation slab of 16-storey monolithic reinforced concrete frame building situated in Kiev, Ukraine. The foundation gap is located 11.65 m below the level of surrounding terrain. Numerical calculations are verified with real measured values of contact stress (published in Lazebnik, 1998) in four different cross sections of foundation slab. The problem is solved as spatial (3D) with complex interaction of пїЅupper structure п...
