Dynamic response analysis of a rock slope under train vibration load

This article analyzed the stress,deformation and stability of a tunnel entrance slope under train vibration load by FLAC3D.Numerical simulation results show that the maximum and minimum principal stress will concentrate at both the tunnel sides and the bottom of the tunnel,and the increscent of maximum principal stress caused by train vibration load is 1～2MPa,and the increscent of minimum principal stress is 0.5～1MPa.The maximum and minimum principal stresses are almost the same as they were loc...
