Under the earthquake load, damage of tunnels is easy to happen because of the fault movement. The finite element method is used to study on the response of mountain tunnel with fault movement under different conditions. The study conditions are fault strike (normal fault, reverse fault and strike-slip fault), fault width and surrounding rock classification. By the simulation, some meaningful results have been obtained. The large area failure is easy to occur under the condition of normal fault. Under the condition of strike-slip fault, the stress of tunnel is concentrated at the position of fault, and the stress in both active and driven plate is small. The influence degree of reverse fault is between the other two faults. The damage range of mountain tunnel is increased with the larger fault width. The tensile stress peak of soft rock is smaller than that of hard rock, but the damage range is larger.
