ANALYSIS THE EFFECT OF RAINFALL ON ENGINEERING SOIL DEPOSITS STABILITY

LI Jun-ye,ZENG Rong(Institute of Geotechnical Engineering,Chongqing Jiaotong University,Chongqing 400074,China)  
Based on the different degree of saturation of the Engineering soil which experienced extreme rainfall in the reservoir area of Chongqing,using the large finite element analysis software GEO-SLOPE to simulate,applying strength reduction to analysis the stability of the deposits.The results show that: due to the natural water content,a certain amount of rainfall in the early stage will reinforce its stability,but under the extreme rainfall,the high-intensity rainfall makes the deposits to achieve saturation rapidly,low-intensity rainfall which lasted a long time makes the deposits to achieve saturation longer,ultimately stability of the deposits reduced,and case occurrence of landslide.
