| 摘 要： | 介绍了饱和-非饱和渗流的计算程序数值模拟方法，该方法模拟了降雨过程中边坡内孔隙水压力的变化，克服了传统降雨边界处理方法的缺陷，考虑了降雨过程中地表边界的条件转化，为以后的径流渗流耦合的模拟提供了良好的基础，为降雨诱发滑坡研究提供了定量分析手段。

| Abstract: | The numerical simulation method of the saturated-unsaturated seepage flow is presented. The pore-water pressure is simulated under rainfall conditions adopted this program. The traditional method handled the rainfall infiltration boundary is conquered, and the real alteration of the rainfall infiltration boundary is taken into consideration to give a good basis for the coupling simulation of the saturated-unsaturated seepage flow and surface overflow. As a result this method is very suitable to the real rainfall process; so It is very helpful to analyzing the reason for rainfall-induced landslides. |
