| 摘 要： | 借助专门的能够控制吸力的四联式非饱和土直剪仪,对清江水布垭坝区古树包滑坡滑带土的重塑样进行了一系列抗剪强度试验,验证了F red lud提出的非饱和土抗剪强度公式对滑带土的适用性,求出了该滑带非饱和土的强度参数;通过在一定基质吸力条件下量测含水率-固结压力之间的关系,指出土-水特征曲线与固结压力相关的特性。

| Abstract: | A series of experiments on the sliding zone soils of Gushubao landslide in Qingjiang are made by means of an advanced shear instrument which can control suction.Based on the experimental results,the formula of shear strength given by Fredlud is verified,some strength parameters of the unsaturated soils are gained,and the relation among matrix suction,water content and pressure are found out.The characteristics of the curve of soil-water in relation to consolidation pressure are also described. |

| Keywords: | sliding zone unsaturated soil strength parameter curve of soil-water |
