| 摘 要： | 基于摩擦学原理及地下水破坏效应，分析研究了地下水对边坡稳定性的影响，提出了真实接触面和视接触面的概念；并运用真实接触面推导了饱水情况下潜在滑面滑动的临界角变化公式。结果表明真实接触面越小，岩土体滑动临界角就越小，而水压的增加促使真实接触面的面积减小，从而加速边坡失稳。

| Abstract: | Based on tribology principle and destructive effect of underground water,this paper studies the influence of underground water on slope stability and puts forward the concepts of real contact face and visual contact face.The formula of critical angle for potential sliding surface under saturated condition is educed using real contact face.It is shown that the less real contact surface,the smaller critical angle for soil mass sliding.Water pressure increase causes reduction of real contact surface and thus accelerates slope destabilized |

| Keywords: | tribology underground water real contact face critical angle destabilization |
