Abstract

Numerical simulation is more and more widely applied in the field of engineering construction and it is proved effective. But if geologic conditions of the construction are complex and the model is large, the conventional modeling method is difficult, time-consuming and inefficient. For that purpose, we decide to use a new modeling method, which is based on the RHINO-KUBRIX and it is intuitive and fast. For example of unfavorable geologic sections of Lirang tunnel in Liangzhong highway, use this method to build 3D numerical tunnel models under a variety of stratums and calculate the ground stress of models, then get the tunnel local stress of surrounding rocks and use FLAC3D to simulate the excavation of tunnel, and through the comparison of Z direction deformation of tunnel lining and monitoring data, analyze the interaction of lining and surrounding rocks in tunnel excavation, then verify the feasibility and the validity of this modeling method, so the research results can provide reference for the numerical modeling in complex geological conditions.
