| 摘 要： | 入渗引起土中孔隙水压力的变化，是影响非饱和土性状的最重要的原因之一。因此，正确地分析和模拟非饱和土入渗过程具有重要意义。通过对一维和二维降雨入渗问题的研究，展示了湿润锋面、地下水位面及孔隙水压力分布随时间的变化，使得对入渗问题的认识更加直观和清楚。

| Abstract: | Infiltration induces the change of pore water pressure in soils, which is one of the most important factors that affect the behavior of unsaturated soils. So, it is of great significance to analyze and simulate the process of unsaturated seepage correctly. By studying on one-dimensional and two-dimensional rain infiltration problems respectively, the movement of wetting front,water table and the change of distribution of pore water pressure are shown. It represents a straighter and more perspicuous view of infiltration. |
