| 摘 要： | 为了简化分析,在模拟斜坡降雨入渗暂态渗流时,通常没有考虑入渗和产流的耦合过程,通过施加流量边界或零水头边界进行地下水渗流计算,通过在FALC中利用内嵌的fish语言,考虑地表径流和地下渗流的耦合以及雨向影响下斜坡降雨入渗过程,并通过算例分析了考虑和不考虑耦合、对斜坡孔隙水压力分布以及考虑各种雨向作用下对坡面积水深度的影响。

| Abstract: | A conventional approach in modeling subsurface transient flow on slopes is to uncouple the infiltration and runoff processes during a storm event and to displace the coupled process by applying discharge or "zero" head pressure on slopes.Filtration of priciptation may be simulated better in FLAC inner language based on the conditions such as coupled surface-subsurface flow directions and vegetation intercept.Comparisons between computed pore water pressure distributions from uncoupled and coupled flows are ... |
