| 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,得到了降雨过程中边坡地下水压力水头、总水头变化、流速的变化规律,研究结果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,which affect slope stability.Considered the effect of rainfall influence,based on saturated-unsaturated seepage theory,numerical simulation on ground water seepage in road slope under persistent rainfall condition was studied using finite element method,and change law of slope seepage field during rainfall process was given.The study can provide important data for road slope stability analysis and landslide prediction. |
