摘　　要：堆积体滑坡广泛分布,需对此类滑坡的形成机制进行了分析,尤其在强降雨条件下｡在降雨条件下,雨水改变了坡体的非饱和土的体积含水量和孔隙水压力,相应地滑带和滑体土的抗剪强度也发生变化｡采用Slope/W软件计算滑坡的稳定性,依据降雨入渗理论和非饱和渗流基本理论,在不同降雨时间,不同降雨强度两种情况下运用Seep/W软件模拟坡体内的渗流情况｡在此基础上,给出关于堆积体滑坡的防治建议。Accumulation landslides are widely distributed,so it is necessary to analyze the formation mechanism of such landslides,especially under heavy rainfall conditions.Under rainfall conditions,rainwater changes the volumetric water content and interstitial hydraulic pressure of unsaturated soil and shear strength of sliding zone and the sliding soil also changes.The stability of landslide is calculated by Slope/W software.According to the rainfall infiltration theory and unsaturated seepage theory,Seep/W software is used to simulate the seepage in slope under different rainfall time and different rainfall intensity.On this basis,the prevention and control suggestions of accumulation landslide are given.
