Foundation Pits of Circular Cross-section
Plevová, Lenka ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The master´s thesis focuses on design of underground sprinkler tank for a shopping centre Sconto in Hradec Králové. The purpose of this thesis is to design and to analyse all parts of this construction. These parts are the roof, the bottom plate and the wall, which is represented by secant piles. Due to the high level of the ground water which causes a great pressure on the bottom of the tank, the solution of the bottom plate represents very important part of this thesis. There were used two programs for an analysis, Scia Engineer 2013 and FIN EC – Beton 3D. Furthermore, the work contains a view and a brief description of methods used for sheeting of foundation pits of a circular cross-section. In the end, this thesis contains the design of two other solutions of bottom plate and its economic comparison.

The design of bridge pillar foundation
Koporec, Vladimír ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The bachelor's thesis discusses the possible ways of surface and and underground establishing the basics of structures and buildings in his first part. In the second, practical part is being resolved a safe and economical foundation of a bridge pillar in the city of Prešov within the given geological conditions. Even though the proposed variants are calculated without the use of computational software, software GEO5 is used to compare the results. software for mutual comparison. The conclusion contains the comparison and evaluation of the results of both approaches.

Energy Piles
Buzgóová, Ivana ; Miča, Lumír (referee) ; Boštík, Jiří (advisor)
In the first part of bachelor thesis, a concept of energy pile is explained and also basic information about usage of geothermal energy, montage of pile, its design and the overall operation of the system is shown. Behaviour of axially loaded energy piles is observed in the individual section. In contrast with other foundation structures, energy piles are also under thermal loading. Next, the main factors of pile behaviour are mentioned, the methods of investigation of energy piles (analytical, experimental and numerical) are described and also characteristics, results from the specific studies that were made in different parts of the world under various conditions. In the second part of the thesis, a simple numerical analysis of energy pile is carried out. The simulation of pile is performed in Plaxis 2D. The description of model, calculation phases are discussed along with achieved results and compared with published studies.

Dewatering of foundation pit - numerical analysis
Krejzar, Vojtěch ; Boštík, Jiří (referee) ; Miča, Lumír (advisor)
The subject of the presented thesis is a foundation pit dewatering numerical analysis. The study is introduced with practical examples and the summary of the necessary theory. Individual subtasks are modeled as two or three-dimensional problem on a chosen foundation pit example. A comparison with analytical methods and theoretical knowledge about the problem is made. The studies focus on specifying the pumped water quantity, the shape of the depression curve, determining the size of the numerical model and the influence of the finite element network density. The steady-state flow cases, water table aquifer, a well system, sheet pile wall cutoff effect, surface drained pit and partial penetration cases are analyzed. The work proposes a method of modeling a well by FEM. The main output is a 3D analysis of a submerged excavation dewatered with a partially penetrated well system.

Design of sheeting on a excavated section of tunnel on a high-speed line Brno-Přerov
Umlauf, Jiří ; Boštík, Jiří (referee) ; Miča, Lumír (advisor)
In first part of the thesis are proposed four variants of retaining structures for deep excavation of cut-and-cover tunnel part. It is nailed slope, pile wall, nailed slope in combination with pile wall and soldier pile wall. For those structures is in following part carried out an economic analysis and the most cost effective variant is chosen. Chosen structure is further analyzed in next part. This analysis is carried out with finite element method in software PLAXIS. As a material model is chosen Hardening Soil model and input parameters were determined by empiric formulas from literature. Behavior of neogene clays, in which is the structure designed, is considered as undrained, by type Undrained A. In the last part of the thesis is described technological procedure of construction this retaining structure.

Foundation of heavy equipment in industrial facility
Minarčík, Jan ; Boštík, Jiří (referee) ; Doněk, Michal (advisor)
The main topic of diploma thesis is foundation of Heavy equipment in industrial facility and the selecting of the appropriate method foundation with respect to the boundary condition. The first part contains the theoretical basis of the chosen special foundation technology. In the second part, there is the design of the foundation itself. To solve the design was used special numerical softwares and also there was some calculation without using it. The necessary design documentation was also created.
