The result shows that when the distance between the fault and the tunnel is less than twice of the tunnel diameter, the fault has significant influence to the stability of the surrounding rock. Also, the distribution and variation of deformation along the two sides of the surrounding rock are no longer symmetrical. The fault imposes maximum influence to the tunnel when the tunnel passes the fault. The influence reduces at the spandrel, and bees relatively small at the skewback. As the distance between the fault and tunnel decreases， the influence of the fault to the stability of surrounding rock increases.With the increase of inclination of the fault, vertical displacement of the surrounding rock at the hanging wall of the fault increases first and followed by decrease,while the vertical displacement at footwall shows opposite tendency.
