| 摘 要： | 通过4组不同含水率千枚岩碎屑土滑带样的三轴排水剪切试验,研究了含水率对滑带土力学特性的影响。研究表明:千枚岩碎屑土滑带样三轴剪切破坏后没有明显的剪切面;应力应变曲线总体上表现为硬化型,且呈现出明显的非线性;随千枚岩碎屑土滑带样的含水率增大,其粘聚力和内摩擦角都是减小的,但敏感性有所不同。

| Abstract: | The impact about moisture content on Mechanical properties of sliding soil is studied through the different triaxial compression tests of sliding soil in different moisture content.The study results show that there is not remarkable shear plane in the triaxial test of phyllite sliding soil;The stress-strain relationship of phyllite sliding soil is turned into hardening and nonlinear modulus.Both of the cohesive strength and the friction angle φ decrease with the increasing of moisture content of phyllite sliding soil,but the sensitivity are difference. |

| Keywords: | sliding soil phyllite triaxial test moisture content |
