As the construction mechanics characteristics of large cross section high speed railway tunnel is complex, the dynamic construction process of Hua jia shan tunnel is simulated by using three-dimensional numerical software. The stress and displacement characteristics of rock mass and surface deformation law are obtained. By comparing with field measured data, the dynamic construction mechanical characteristics of large cross section high speed railway tunnel are concluded which provides support for construction scheme optimization of this project.
