镇江市山体边坡土体特性为非饱和土，土体含水量在很大程度上影响着非饱和土应力状态。文章通过非饱和土强度试验研究分析表明，随着含水量的增大，非饱和土的粘聚力逐渐增大，当含水量增大17.09%附近时，粘聚力有极大值；随着含水率的逐渐提高，其内摩擦角逐渐减小，当含水率为23.82%附近时，内摩擦角从近似线性单调递减趋于平缓。该试验分析结果为建立雨水入渗与边坡稳定之间的关系提供了理论基础。

Zhenjiang City mountain slope soil characteristics for unsaturated soil , the soil moisture content has a great influence on unsaturated soil stress state. In this paper ,the experimental study on unsaturated soil strength analysis shows that,with the increase of water content,unsaturated soil cohesion increases gradually,when the water content increases about 17.09%,cohesion is of great value;with increasing water content,the internal friction angle decreases,when the water content is around 23.82%,the internal friction from the angle ofapproximate linear decrease monotonically leveled off.The results of the test ,and provides a theoretical basisfor the establishment of rainwater into the relationship between the seepage and slope stability.
