Důležitost průzkumných štol pro realizaci tunelů

Abstract

There has been a great progress in realization of tunnels in the Czech Republic in the last years. The increased number of realized motorway tunnels is connected with an extension of motorway network to the places which require realization of tunnel objects, for example: motorway D8 (tunnels Panenská, Libouchec, Prackovice and Radejičín – The Ore Mountain ridge). Attached to the necessity of tunnel construction there is a need to carry out detailed geological survey of a land which the tunnels pass through. There are carried out exploratory gallery deeps for verification of geological and hydrogeological conditions for tunnels completion. The exploratory gallery deep evaluation should answer the questions which are important for a project of thrusts of tunnel constructions. This bachelor thesis is focused on a comparison of the two realized exploratory gallery deeps in a framework of a tunnel building. There are discussed exploratory gallery deeps of a Prague circular, site 514 Lahovice – Slivence and motorway D8, site 0807/II Knínice – boundary bridge, part G – tunnel Panenská. In the introduction of the thesis there are specified problems within the design of the communication line where a realization of a tunnel object is necessary. Another part deals with reasoning of realization and a design of exploratory gallery deeps. Next there is an evaluation and comparison of results of realised exploratory gallery deeps. In conclusion there is an evaluation of a design purposefulness and realization of exploratory gallery deeps.
