Abstract This displacement of the rock wall is not convergence in a long time after excavating in F7 fault of the Wushaoling tunnel, and the time for lining executed can not meet the request of "The Code for Design of Railway Tunnel" , because the rock is weak and soft with complicated and high earth pressure. This paper indicates that the designing parameters are feasible and safe through analyzing the safety of lining by using FEM and surveying, the second lining should be carried out in time in order to control big displacement.
