Tunnel excavation design is an important content in the civil engineering, many researches are done based on the linear failure criterions by the analytical solution and numerical solution, but seldom researches are done to apply the nonlinear failure criterion in describing the surrounding rock mass after tunnel excavation, although nonlinear failure criterion shows great advantages over the linear failure criterion. Fortunately, Many scholars have done some work to study the rock mass characteristic based on the nonlinear failure criterion by the analytical solutions, but the analytical solutions can only be applied in analyzing the problem with simple geometry, simple boundary conditions. In order to explore a new way for geotechnical design, the numerical solution is proposed. And the numerical modeling method and simulation model is introduced, both the analytical method and numerical method are described based on the nonlinear failure criterion, then the stress and deformation of surrounding rock mass after tunnel excavation are analyzed whose results are compared to verify the numerical calculation method.
