Abstract

This paper applied the finite element analysis software MIDAS/ GTS, taking use of ground structure method analysis stability in the process of tunnel excavation and support the western hills. The results showed that the different sections during the excavation the maximum principal stress within the rock focused on steel feet, it is timely lock pin bolt when steel erection, taking use of small catheters grouting and other methods reinforcement of the rock arch foot when necessary. From the perspective of lining deformation, the maximum deformation at the end of the foot and the location of the vault subsidence, so we should pay attention to the monitoring of settlement of vault, the gradual excavation of core soil, ensure the construction and structural safety, and should be based on engineering facilities in time to control the chamber deformation.
