摘　　要：本文针对在降雨条件下的边坡失稳问题,研究了降雨入渗情况下边坡内非饱和渗流场的变化以及渗流场的变化对边坡失稳的影响机理,结合广东省梅河高速公路边坡实例,进行了边坡内渗流场数值模拟,得出了有意义的结论。In order to solve the problem of sloping unstability in the condition of rainfall, the paper studies the changes of unsaturated seepage field when rainfall and the influence mechanism of seepage field work on the slope. Combined with Meihe expressway slope project in Guangdong province, numerical simulation of seepage field is carried out, some significant conclusions are obtained.
