Excavation pit in Olomouc
Plevová, Lenka ; Masopust,, Jan (referee) ; Miča, Lumír (advisor)
The bachelor´s thesis focuses on sheeting of a construction pit in Faculty hospital of Olomouc. The purpose of this thesis is to design sheeting construction and describe technological process of buiding the chosen construction type which is in this work represented by once anchored pile wall with the large axial distance. In adition, sheet pile wall was analysed in two various geotechnical programs, GEO5 and Plaxis 2D. Furthermore, this work contains a view and a brief description of other methods used for sheeting constructions. In the end, this thesis deals with economic comparison of designed type of pile wall with another two types, tangent pile wall and secant pile wall.

The providing of decontamiantion pit for the environmental purposes
Bůžková, Eliška ; Lokos, Jan (referee) ; Horák, Vladislav (advisor)
As the trend in environmental care grows, the emphasis on removing the old environmental burdens is bigger. This thesis is dedicated to the case when the soil was contaminated by products of gas industry in the area of Jihomoravská plynárenská, a.s. in Brno - Zábrdovice . The aim of this work is to select the appropriate remediation technology and shoring remediation pit in mentioned locality. Diploma thesis also includes design and assessment of selected construction sheeting calculated by the method of dependent pressures, technology design and implementation of construction drawings.

Sheeting of foundation pit
Šajuk, Mykola ; Kliš, Lumír (referee) ; Glisníková, Věra (advisor)
The bachelor's thesis describes the design and static assessment of the excavation of the construction pit realized for the construction of the Homole tunnel of the D35 Ostrov – Vysoké Mýto highway section. The introductory part of the work summarizes the basic input information about the location of interest, including the outputs of the engineering-geological survey, and provides an overview of the possibilities of securing construction pits. The core part of the work describes the design, assessment and economic evaluation of three selected variants of the stocking, subsequent evaluation of the results of the selection of the most suitable variant. The resulting structure is supplemented with drawing documentation, which is part of the annex.

Optimization of the Material Parameters Based on Retaining Wall Monitoring
Koudela, Pavel ; Chalmovský, Juraj ; Miča, Lumír
Geotechnical monitoring is usually used for the verification of designed constructions. A result of the monitoring could be used as an alternative for the determination of material parameters involving optimization procedures. The optimization procedure will be used as a tool for determining material parameters using the inclinometer measurement of a retaining wall. The simple script involving data processing between Plaxis and optimization procedure Particle swarm optimization (PSO) was written. In this way, the input parameters of Brno Miocene clay for the Hardening Soil model were optimized. The results of the optimization procedures confirm the hypothesis, the optimization could be used as a useful tool for determining the material parameters of soils.

Numerical analysis of stability of retaining structure in cohesive soils
Fejfarová, Aneta ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
The bachelor thesis deals with numerical modeling of excavation using finite element method in the Plaxis 2D software. Triple-anchored retaining structure is founded in a less permeable cohesive soils. There are described loss of stability, types of the calculation and material model (Hardenig soil model used in the mathematical model) in the theoretical section of this bachelor thesis. Mathematical model of the excavation was described in the practical section of this thesis, specifically first limit state. Part of the thesis is an evaluation of the degree of stability over time, pore pressures and critical shear surfaces.

Comparison of two alternatives of deep excavation design
Krejzar, Vojtěch ; Miča, Lumír (referee) ; Chalmovský, Juraj (advisor)
The thesis focuses on numerical modeling of a 30 m deep excavation using the finite element method (FEM). The excavation is situated in Luzern, Switzerland. The subsoil is formed by inclined sandstone or siltstone layers; one of them tends to form a dangerous slip surface. The bachelor’s thesis compares 2 alternatives: Alternative A represents a combination of an anchored pile wall and sprayed concrete in the lower part of the excavation, Alternative B represents a full height anchored pile wall. The thesis comprises of the description of modeling, determination of material parameters and structural members’ inputs, defines calculation phases and predicts the structure deformations. The mathematical model is created using PLAXIS 2D software.

Design of deep excavation on the street Provaznikova
Koudelková, Ivana ; Svoboda,, Petr (referee) ; Miča, Lumír (advisor)
This diploma thesis describes the design and static assessment carried shoring excavation pit for the construction of a multifunctional building in Brno Husovice. Introductory part summarizes the basic input information on the area of interest, including outputs of engineering-geological survey and gives an overview of the options pits. The main part describes the design and assessment of selected variant of shoring, the subsequent evaluation of the results and the technological progress of construction. The proposed design is complemented by structural calculations and construction plans.

Design of the Foundation Pit Sheeting
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.
