摘要
从人工降雨实验和数值计算二方面研究雨水入渗坡面所产生的地下水流的进展过程,给出了变化坡度所对应的地下水位的形状图,比较了降雨产生地下水流的实验与仿真结果。对斜面的大部分区域,数值仿真结果和实验观测的数据一致。说明了当斜坡往下变缓时,地下水位在斜坡变化处有个峰值导致小规模的滑坡从而引发大规模的滑坡。
The development of subsurface flow in soil slope due to rainfall infiltration was studied with both artificial rainfall experiment and numerical analysis. The shapes of ground water levels for changing slope were shown. The comparison between simulation results and subsurface flow observed in the rainfall experiment was obtained. For the greater part of soil slope, the simulation results showed a good agreement with the data observed in the rainfall experiment, When a slope was gentle downward, the peak ground water level was found at this changing point. The peak ground water level should generate the largescale landslide, which was preceded by a small-scale landslide.
