摘要：
This paper employs pulse-like ground motions (PLGMs) and presents a predictive model to estimate the earthquake-triggered displacement of slopes in the near-fault region based on the coupled stick-slip-rotation (CSSR) analysis. The efficiency of ground motion intensity measures (IMs) is appraised to predict the seismic-induced displacement when a slope is affected by PLGMs. The combination of suitable IM, yield acceleration coefficient, slippage length, and period ratio were employed to develop the predictive model. The resulting predictive model provides seismic sliding displacement with a reasonable standard deviation. The proposed model is compared with two previous models presented based on the PLGMs and CSSR approach.
