Abstract：
For the safe construction and long-term stability of understructure work, in this paper was programmed by the finite difference software based on its secondary development function. Then, an indoor uni-axial creep test of the rocks soaked in water was employed to verify the rationality of this model. The model was applied to calculate the No.1 tunnel program at Jianfengding in two different methods. The results suggested that the underwater directly expands the rock deformation area, which have a negative effect on the safety and stability of the tunnel construction. Thus, based on the calculation, a reinforcement scheme was proposed to improve the stability of the tunnel and the rational time to carry on the tunnel second support was predicted in this paper.
