Securing of Foundation Pit in Brno for the Underground Garage at the Janáček Theatre
Zapletal, Adam ; Štefaňák, Jan (referee) ; Masopust, Jan (advisor)
The bachelor´s thesis deals with the sheeting construction real construction pit underground parking garage at the Janáček Theatre in Brno. It contains the description of the possible solutions to the appreciation of their advantages and disadvantages. The goal is to choose one of these methods based on evaluation of engineering-geological survey appropriate method to ensure that the construction pit. For this method to perform static analysis and process design documentation.

Design of excavation for reconstruction of shopping centre
Červenka, Jan ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The thesis is divided into three parts. In the first one it deals with the design and the assessment of the once-anchored soldier pile wall, which provides an excavation for the reconstruction of the shopping centre Prior in Zlín. The retaining structure is designed according to the limit state method, using the GEO5 software and the Excel spreadsheet editor. In the second part, the thesis deals with the price comparison of the classic version of the soldier pile wall with soldier pile, IPN profiles, with over one-pole anchorage with the help of the buckle, with the variant with larger spread, where the soldier pile from the pair of UPN profiles are adapted for anchoring. The third part solves the problem of the distribution of a lateral ground pressures along the length of the soldier pile wall. For comparison with the empirical methods of design of lagging, the results of normal pressure from the mathematical model, solved by the numerical analysis, the finite element method, were used in the Plaxis 3D program. Hardening soil model was used as the material model.

Design of excavation in the Brno city centre
Kováč, Vladimír ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The work deals with the problem of the ultimate and serviceability limit state of a once-anchored retaining structure of an excavation on Krenova street in Brno. The calculation of the ultimate limit state is solved manually and provides an input into the serviceability limit state, which is solved by means of a numerical analysis using a finite element method. To calculate the serviceability limit state, these constitutive models: Mohr-Columb, Hardening soil and Hardening soil small strain model are used.

Valkó, Attila ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The bachelor´s thesis deals with the design of the foundation pit sheeting of a multifunctional building in Brno - Pisárky. The thesis contains the description of various styles of foundation pit sheeting. The purpose of the thesis is designing an appropriate method of sheeting, in this case an anchored excavation method is used. Statistic calculations were performed by program GEO5.

Dilatancy of soils as a factor influencing the bearing capacity and load - displacement response of deep foundations
Dvořák, Tomáš ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
In theory of soil mechanic the dilatancy has a significant influence, which may fundamentally affect bearing capacity and behavior of geotechnical constructions. In the past it was difficult to include influence of dilatancy directly in to calculation, but now with development of numerical analysis and growth of computer performance it is much easier. In this work there are introduced fundamental dilatancy models and phenomen called constraint dilatancy, which causes stress changes in soil or at soil – construction interface. This stress changes may lead to higher bearing capacity. In this work, the effect of constraint dilatancy is focused on bored pile’s shaft. Next target of this work is including dilatancy to calculation. By empirical methods, by direct application with theory of cylindrical cavity expansion and last by numerical calculation with finite element method in software Plaxis with using the Hardening Soil model.

Small strain stiffness of soils and methods of its measurement
Havlíček, Jaroslav ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
This thesis consists of theoretical and practical part. Firstly, the soil behaviour at small-strain range and its physical nature are described. Subsequently, the individual soil parameters affecting the value of small-strain shear modulus and the shape of the stiffness reduction curve with increasing shear strain are described. The individual methods of measuring the small-strain stiffness in the laboratory and in-situ with a more detailed explanation of the evaluation of measurements using bender elements are given in the last chapter of the theoretical part. In the practical part, a device for measuring small-strain stiffness using bender elements was put into operation. The used laboratory equipment is described first and then the parameters of tested soil are given. The main chapter is measurement and evaluation of the impact of software and hardware settings and the influence of effective stress of soil on the small-strain shear modulus that is compared with predictions of empirical expressions from the literature.

Valkó, Attila ; Boštík, Jiří (referee) ; Doněk, Michal (advisor)
Diploma thesis deals with securing of foundation pit of family house in given geological conditions situated in Brno-Kohoutovice. The aim of the thesis is to list possible solutions of securing foundation pits in general and solve this geotechnical problem with an appropriate solution. Static calculations were performed by geotechnical software GEO5.

Foundation of Apartment Building in Třeboň
Jurníček, Lukáš ; Glisníková, Věra (referee) ; Svoboda, Petr (advisor)
The bachelor thesis deals with the theme of the apartment building foundation. Its objective is based on studies of expert resources and static assessment to design an appropriate way of building construction foundation. In the theoretical part of the bachelor thesis, the author is concerned with the most frequent possibilities of establishing common residential house, the area, and underground foundation on deep soils improved. In the second part, the author makes choice of a particular method of foundation (deep while using piles) and applies it to the calculation of the real structure. The static calculation has been described and consequently manually processed, and finally verified within the program GEO 5. The work also includes an overview together with a brief description of other information sources to be used for the creation of static calculation.

Design of the Foundation Pit for Apartment Building
Šobáň, Jakub ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The bachelor´s thesis focuses on meeting of a construction pit forresidential building Kadetka in Brno. The purpose of this thesis is to design meeting construction and describe technological process of buiding the chosen construction type whichis in this work represented by once anchored meeting structure. This meeting structure was analysed in geotechnical program GEO5.
