摘要
用数值解析研讨了降雨渗透变化坡面的地下水流的进展和衰退过程。对坡度无变化、坡度变缓和坡度变陡三种情况下的地下水流的过渡过程进行仿真。做出变化坡度所对应的地下水位的形状图。数值计算验算了降雨的方式,斜坡地层的形状以及坡度的变化对地下水位进展和衰退过程的影响。仿真分析了地下水位的峰值。
The development and decline of subsurface flow in soil changing slope due to rainfall infiltration were studied with numerical analysis. Numerical calculations were performed for three cases, where the slope is constant, gentle downward or steep downward. The shapes of ground water levels for development and decline of subsurface flow were shown. In numerical calculations, the effects of rainfall pattern, shape of slope layer and changing slope to the development and decline of subsurface flow were examined. The peak ground water level was analyzed on simulation.
