摘　　要：以雅砻江某边坡为例,模拟该边坡不同时段随降雨产生的饱和—非饱和渗流问题,得到各个时段边坡的负孔隙水压和体积含水率并且通过云图表示,计算该边坡各个时段安全系数,得出降雨条件下该边坡安全系数随着降雨条件的变化规律。Take a slop on the Yalong river area for example,we can simulate the slope generated with the rain saturated-unsaturated seepage problems at different times.In each period the slope s negative pore water pressure and volume of water content can be clouded.Successive calculation of safety factors,obtained variation regular of safety factor under rainfall conditions.
