| 摘 要： | 降雨是影响道路边坡稳定的主要因素之一，根据岩土饱和-非饱和渗流理论，考虑降雨入渗的影响，利用有限元方法，对强降雨条件下公路边坡地下水渗流场动态进行了数值模拟，得到了边坡地下水压力水头、总水头变化、流速的变化规律，为道路边坡的稳定性分析和滑坡预测提供重要的分析数据。

| Abstract: | Rainfall is one of the important factors affecting slope stability. Considered the effect of rainfall infiltration, based on saturated-unsaturated seepage theory, numerical simulation on groundwater seepage in road slope under persistent rainfall condition is studied using finite element method; and change law of slope seepage field during rainfall process is given. The study can provide important data for road slope stability analysis and landslide prediction. |

| Keywords: | rainfall infiltration seepage road slope numerical simulation |
