Preliminary study of the construction of a tram tunnel in Brno
Kuhajdik, Adam ; Janků,, Hynek (referee) ; Horák, Vladislav (advisor)
The selection of a suitable tunneling technology within the territory of the town has an essential impact on behaviour of surrounding buildings. The thesis presents basic applicable methods. The selected method is simulated in a mathematical model whose input parameters are defined according to geotechnical investigation and by calculating from cone penetration test. Furthermore, the thesis deals with parametric comparisons of a constructional element in dimensioning, horizontal and vertical shift of this element and simplified comparison of steel and concrete prices. This thesis also contains re – comparison of construction behaviour within a model with real deformations which are measured using an inclinometer in situ.
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.
