| 摘 要： | 对降雨渗入坡面土壤所产生地下水流的进展过程进行了数值解析计算。做出了不同降雨方式所产生的地下水位的形状图。仿真结果说明渗透坡面的地下水位在斜面的中、下方区域内与斜面平行地上升。近似解说明了水位的上升与降雨强度和时间成正比，与土壤的有效孔隙率成反比。讨论了降雨的方式，降雨的强度，渗透系数以及斜坡地层的形状对地下水流进展过程的影响。

| 关 键 词： | 地下水流 降雨强度 有效孔隙率 渗透系数 |

| Abstract: | The development of subsurface flow in soil slope due to rainfall infiltration has been studied with numerical analysis.The shapes of ground water levels for different rainfall pattern have been shown.Simulation analyses for steep slope indicate the ground water level rises in parallel with slope in the middle and lower portions of the slope.Approximate solutions show that the ground water level rises in proportion with rainfall intensity,time and inverse number of the effective porosity of the soil.In numerical calculations,the effects of rainfall pattern,rainfall intensity,coefficient of permeability and shape of slope layer to the development of subsurface flow are examined. |

| Keywords: | subsurface flow rainfall intensity effective porosity coefficient of permeability |
