Study on Stability of Round Tunnel Surrounding Rock

摘要：

　　Tunnel excavation will lead to the immediate surrounding rock unloading caused by the surrounding rock stress release,the stability of the surrounding rock have a certain impact.In this paper,finite element software ANSYS and finite difference software FLAC3D are used to simulate the excavation and lining process of circular tunnel.The influence of excavation on the rock stability around circular tunnel is analyzed,and the effect of applying lining on the stability of surrounding rock is analyzed.Evaluation criteria selection hole displacement,stress and plastic area of three factors.
