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.

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.
