The study shows that the foot of slope in the process of rain is easiest to be destroyed, and that with the increase of rainfall intensity and time, the shear stress is also increasing and that the face of the slope is more easily to be destroyed. 说明坡脚在降雨过程中最容易达到破坏状态,且随着降雨强度、时间的增加,沿坡面的剪应力也不断的增大,坡面发生破坏的可能性也越来越大。
To contrast before excavation, the horizontal displacement increased clearly in part of body foot on the excavation face, the increased concentrating strip of shear strain extended further. 与开挖前相比,堆积体坡脚开挖面上部水平位移明显增大,剪应变增量集中带进一步延伸,易沿开挖面发生垮塌破坏。
