Then through dynamical analysis, every instantaneous acceleration distributing of slope under dynamical earthquake can be got too. According to this result, adding earthquake force to structure by way of inertial force, this paper analyses the slope stabilization by using FEM strength reduction method and gains every instantaneous safety factor and its corresponding slide.

By these principles, programs of FEM stabilization analysis for each moment are organized.
