Abstract
In order to study the influence of earthquake and rainfall on the dynamic characteristics of gently inclined slope,a slope similarity model test was carried out on a large shaking table,to analyze the changes of soil pressure,pore pressure and displacement of loess slope under the coupling action of earthquake and rainfall.The results showed that the amplification effect of acceleration increased with the increase of earthquake intensity under the influence of rainfall before earthquake,but the amplification effect of acceleration on slope was weakened by rainfall before earthquake.The soil pressure of the slope increases with the decrease of the altitude,and the dynamic pore pressure in slope varied greatly with the rainfall before earthquake.The influence of rainfall before earthquake increased the moisture content of loess and decreased the slope stability.关键词
