摘要：Soil-rock slope is a structure of slopes distributing widely in the world, but the calculation model of its stability is always set as uniform soil model under the influence of earthquake, and the effect of rock distribution on the slope can’t be considered comprehensively. Therefore, based on the method of finite element non-linear time-procedure, this paper analyses the acceleration response of slopes under the influence of earthquake with different rock distribution. Results show that the distribution of rocks have great influence on the accelerated response characteristic, and the main findings are as follows: (a) the accelerated time-history curve can filter the high frequency waves; (b) the free-surface has amplifying effect on seismic waves; (c) the acceleration response curves have different degrees of “biased”. Through above analysis, it’s expected to provide some reference for the stability analysis of soil-rock slope and reinforcement scheme under the influence of earthquake.
