Pseudo-static analysis method is used for seismic slope stability analysis specified by currenttechnical code. In fact, safety factor of seismic slope stability should be a function of time. Dynamic safetyfactor based on nonlinear analysis method is employed for characterizing dynamic stability of rock slope.The main steps are as follows. 1. Determining the parameters of the constitutive relationship; 2. Computing the initial stress of slopeby static analysis; 3. Computing dynamic stress of slope by dynamic...
