Abstract :
Rock material is one kind of physical nonlinear material. Under deep buried condition, the deformation of rock system in tunnel belongs to geometric nonlinear behavior. Based on strain-softening model, applying the large deformation calculation method, the numerical simulation is conducted for construction process of a deep buried tunnel. The data information of excavation unloading deformation process of rock is extracted. Using the C-C method, the nonlinear dynamic character of rock deformation evolution is studied.
