以甘肃一黄土滑坡为例,将流固耦合理论引入边坡的稳定分析,结合数值分析软件FLAC,研究了边坡在不同降雨入渗深度下位移、速率的变化情况以及边坡破坏场的发展规律,提出了以位移和速率为标准的边坡稳定性评价方法。结果表明：随着降雨的入渗,位移和速率有不断增大的趋势,降雨入渗4 m后,位移和速率显著增大,边坡破坏面处于贯通状态,坡体达到临界滑动速率,直至推动整个坡体向下滑动而形成推移式滑坡。

Taking a loess landslide in Gansu for example,the theory of fluid-structure interaction is introduced in slope stability analysis.Combined with numerical analysis software FLAC,the changes of slope displacement and velocity in different depths of rainfall infiltration and the development law of damage field are analyzed,and the evaluation method for slope stability based on displacement and velocity is put forward in this paper.The results show that with the rainfall infiltration,displacement and velocity of slope are increasing;after rainfall infiltration depth reaches 4 m,displacement and velocity increased significantly.At this time,slope failure surface is in break-through state and the slope reaches the critical rate of landslide until the entire slope is pushed to slide down to form landslide.
