SEISMIC SAFETY DEGREE EVALUATION FOR STABILITY OF HIGH ARCH DAM ABUTMENT

摘要：

A new FEM seismic stability safety evaluation for high arch dam abutment is suggested in this paper. The shear strengths on the sliding surfaces are divided by different strength-reduction ratios and the seismic analysis is made after the accomplishment of the static analysis. The seismic safety factor is corresponding to that all the elements on the sliding surface are sliding under earthquake loads. The earthquake waves are put on the artificial boundaries and the viscous radiation conditions are used to simulate the outwards wave absorption. An example is given to explain how to evaluate the seismic stability safety for high arch dam abutment this method.
