Stabilita portálů tunelu Bikoš

Abstract

This diploma thesis deals with the geotechnical monitoring of Bikoš tunnel, specifically with the analysis of convergence measurements of geodetical portal points located on the north and south portal walls for excavation, and with analysis of convergence measurements of geodetical points located on 4 portal inclinometers. For the purpose of description, evaluation and visualization of acquired data, the simplified 3D triangulated portal models were created. Input raw geodetical data were processed by software for usage and the output of the thesis are the vectors of point movements which followed whole history of portal and tunnel excavation, as well as the description of trigger limits.
