Stability Analysis of Main Structure for an Open-Cut Metro Station

Based on a metro station background of the line 3 west extension engineering of Kunming metro line co.LTD. On the basis of geological survey and indoor geotechnical mechanics experiment, the 3D geological model was established by three-dimensional finite difference method FLAC3D. Stability of main structure for the metro station was analyzed. The analysis results provides a reference for safety operation of the metro station.

Reliability Analysis on Stability of Retaining Wall

The retaining wall structure reliability calculation model was established by identifying the stability reliability analysis function of retaining wall according to the geotechnical mechanics parameters’ interval characteristic. The method in this paper has been applied to the engineering examples, the results shows it is reasonable and practicable. The influence of geotechnical mechanics parameters on the retaining wall stability reliability index that was discussed in this paper has a certain reference value for engineering.
