| 摘 要： | 以FLAC2d为基础，利用其自带的fish语言编制了考虑非饱和土水气两相非饱和渗流-地表径流耦合程序，通过算例分析表明，为了准确地评价降雨对边坡稳定性的影响，建议采用耦合边界进行计算，同时考虑水气两相的流动。

| Abstract: | Based on FLAC2d,the program considering unsaturated soil water-gas two-phase permeation and surface runoff is prepared with fish language.It is indicated from calculation that for precise evaluation of rainfall influence on side slope stability,coupling boundary shall be adopted for calculation and water-gas two-phase flow shall be also considered. |

| Keywords: | unsaturated permeation surface runoff coupling side slope stability |
