Návrh primárního ostění průzkumné štoly – doplňkový geologický průzkum nové trasy metra D

Abstract

The subject of the diploma thesis is to create an alternative design of primary lining for the exploration gallery in the additional geological survey of subway route I.D on its part Pankrác-Olbrachtová. The introduction is devoted to the description of the purpose of the construction, its construction objects, construction technology and main used exploratory works. Accordingly, I described three already realised exploration galleries and its utilization. The practical part of the thesis consists of design of the profile size of exploration gallery in the tunnel profile. Based on the outcomes from the drilling exploration from preliminary and detailed survey, there were compiled two geological profiles (located in the route of future line of subway D) and mathematical models. The exploration gallery will be placed into these profiles. For the individual profiles I designed the parameters of the primary lining, anchoring and stabilisation elements. At the end of the thesis I evaluate the results gained from software Plaxis 2D with warning conditions for individual technological classes of cutting out and with real generated deformations in the lining of the exploration gallery, together with surface drop.
