Reconstruction of the railway tunnel
Nekl, Jiří ; Horák, Vlastimil (referee) ; Horák, Vladislav (advisor)
The diploma thesis engages in the reconstruction of railway tunnel Domasovsky that is situated at the track section Olomouc – Krnov. It illustrates the current state of the construction and the geotechnical conditons of the area of interest, it also presents the potencial solutions. The design is verified by stuructural analysis, the design documentation and technical report are also enclosed.

Mining and access shaft of the pilot adit with extended launch chamber
Kuhajdik, Adam ; Horák, Vlastimil (referee) ; Horák, Vladislav (advisor)
The diploma thesis deals with the design of a mining and access shaft with an extended launch chamber for the Vinohrady exploration adit in Brno. The requirements to be met by this underground work are defined. Based on an analysis of the applicable shaft sinking methods, two implementation procedures have been proposed. The combination of a drilled pile wall with extensive use of jet grouting appears to be preferable. This procedure is further elaborated in 2D and 3D models with static design assessment of the different structural parts and phases. The work further discusses displacements in the modelled environment and displacements on the structure. The static design of the shaft is complemented by a safety analysis of the embryo face of the exploration adit. A bill of quantities of the selected technical solution is also included in this work. The work with numerical models includes a comparison of the results of 2D and 3D models.

Technical gallery under the railway
Michaljaničová, Jana ; Horák, Vlastimil (referee) ; Horák, Vladislav (advisor)
The focus of this master thesis design static assessment of shotcrete lining belonging to underground gallery for water supply. This object is a part of larger project called „Uzel Plzeň, 3. stavba – přesmyk domažlické trati“. The gallery with length almost 100 m leads directly under two double-track lines with height traffic importance and two factory sidings. The thesis deals with the recommendation of a suitable technological procedure for excavation and excavation stability. It also includes design of both primary and secondary shotcrete lining. The assessment is based on the evaluation of the outputs of two characteristic cross-sections processed in Plaxis 2D. The outputs consist of information on internal forces, deformations and state of stress in the surrounding rock. Based on this information, a structural design is performed

Analysis of the way of the route through the sloping area of the D1 motorway in the SR
Horňáková, Lenka ; Horák, Vlastimil (referee) ; Horák, Vladislav (advisor)
The construction of motorways in Slovakia faces a series of geotechnical problems due to the mountainous relief. One of these problems is also discussed in this diploma thesis, where the motorway route is led through a landslide area. The aim of the thesis is to compare two different proposals of the D1 motorway in part of Hubova - Ivachnova section. The theoretical part deals with the issue of slope movements in connection with transport line constructions. In the practical part, the proposals for specific solutions of the high embankment route variant and variant with the bridge are discussed. Both variants are designed in the Plaxis numeric program. Subsequent comparison and evaluation of variants is performed in relation to the degree of stability, deformation, structural stress and construction costs.
