Numerical Analysis on Surrounding Rock and Supporting Structure Stress Response in the Process of Lingjiao Tunnel Construction

Qin Yu-bin

Abstract

In order to get the stress response rules of surrounding rock and supporting structure in the process of tunnel excavation,the article took Censhui Expressway Lingjiao Tunnel as the research object,conducted the numerical simulation on the stress response rules of surrounding rock and supporting structure in the construction process through applying the finite element analysis software MIDAS/GTS,and analyzed the surrounding rock stress conditions in the tunnel construction.
