Tunel Milochov - předpoklady a skutečnost

Abstract

The diploma thesis is excluded from the investigation of the Milochov railway tunnel. The first variant of the original lining model was developed from the original project documentation, which was prepared before construction began. The second variant of the proven lining model was developed from the modified project documentation.The modification of the project documentation includes the area of the eastern portal on the basis of the real geological conditions. The inaccurate composition of the rock environment was caused by the absence of a exploratory gallery and insufficient drilling contamination of the area. Modification of project documentation resulted in new equipment of excavation classes V.b VP, V.c and VI. PLAXIS 2D. The output of the thesis is a numerical analysis of the behavior of the active lining in individual equipment classes.
