Comparison of Russian, Chinese and European seismic design on pseudo-static seismic coefficient in slope analysis

Abstract

Most design codes and specifications recommend a simple pseudo-static approach for the analysis of slope stability under seismic conditions. The codes in different countries appoint different pseudo-static seismic coefficient. The present work list different seismic coefficients in Russian, Chinese and European codes. A sensitivity analysis of a case slope was carried out using GeoStudio, then determined that the stability of the slope is more sensitive to material cohesion and seismic coefficient than material density and friction angle. It‘s shown that the chosen of the seismic coefficient has a big effect on slope stability.
