Concrete retaining wall
Gric, Pavel ; Zich, Miloš (referee) ; Strnad, Jiří (advisor)
This thesis is about design and assessment of angular retaining wall from reinforced concrete. There are analyzed effects of loads from each design approach listed in standard ČSN EN 1997. The retaining wall is designed according to the standard ČSN EN 1992.

Design of Gravity Wall in Terms of Flysch Geology
Horňáková, Lenka ; Fiala, Radek (referee) ; Brdečková, Helena (advisor)
The bachelor´s thesis is divided to two main parts, from which first is focused on the theory of reinforced concrete retaining walls. The second, practical part deals with design and assessment of the cantilever breast wall supporting the sloping slope in place of annex of congress hall situated above the northern wall of Tatra´s hotel in Velke Karlovice. The labor contains processing of geomorphology and geology surrounding area, load, sample calculation cantilever breast wall and its assessment.

Retaining Walls
Pospíšil, Jan ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The objective of thesis is to create a comprehensive overwiew of the most commonly used retaining walls in the Czech Republic and to characterize their properties, method of assessment, advantages, disadvantages or causes of failures. Based on these findings will be designed selected type of retaining wall in Rebešovice.

Flexible buried structures
Houšť, Vladimír ; Hrdoušek,, Vladislav (referee) ; Barták,, Jiří (referee) ; Klusáček, Ladislav (referee) ; Stráský, Jiří (advisor)
The thesis is devoted to analysing of flexible buried arch structures. Modelling of the flexible concrete arch is carried out via a nonlinear finite element model that accounts for soil constitutive relations, soil-structure interactions, sequential construction stages and soil compaction. Advanced FE-model was verified by measurement obtained by full-scale field testing of two buried arches. Mathematical optimization methods of genetic algorithms and Levenberg-Marquardt method are applied to already calibrated complex computational models in order to reduce bending and associated flexural stresses in the concrete section of buried arch. Centre line of the arch is parameterized by cubic Bezier curve to reach interpolation of thrust line. Optimization technique is applied with extensive parametrical study which shows the optimal shapes for buried arches of various span/rise ratios, backfill depths and foundation soil types. For practical application are given coordinates of Bézier curve control polygons of particular resulting shape. Subsequently is applied optimization method for a theoretical reduction of tensile stresses obtained by shape optimization of previously verified numerical model of buried arch. Comparisons of earth pressure, bending moment axial force and deflection of flexible structure during sequential construction of different span/raise ratios of buried arches are presented. The behaviour of flexible buried arch with effect of local traffic load model LM1 has been analysed via 3D finite elements model with respect to different depth of backfill above crown.
