| 中文摘要: |
| 用饱和-非饱和达西渗流理论对降雨入渗的复杂渗流场问题用有限单元法求解，在理论上进行了深入的研究。文中特别提出了降雨入渗边界条件及非饱和逸出面边界条件(包括降雨中间停雨时期边界条件)在渗流场求解中的正确处理方法，提出和定义了描述土体渗流特性的极限含水率和蒸逸系数的两个新概念。两个算例的数值试验也进一步表明，文中所用的降雨入渗渗流场分析方法结果合理，实用性强。 |
| 英文摘要: |
| The finite element method is applied to solve the complicated Darcy's saturated unsaturated seepage problem caused by raining infiltration. In the solution, the boundary conditions of raining infiltration and unsaturated exit surface of seepage are strictly processed numerically. Two new concepts and definitions of extreme rate of water content and evaporation coefficient of porous seepage media are proposed. The reasonability of the proposed method is verified by two examples. |
