| 摘 要： | 对兰州原状黄土不同剪切方位、不同含水量试样进行了一系列常规三轴不固结不排水剪切试验研究.根据三轴剪切试验结果,分析了含水量和剪切方位对兰州黄土剪切强度参数的影响,得出原状黄土的粘聚力和内摩擦角并不是一个常数,而是随着含水量和剪切方位的变化而变化的结论,解释了其影响原因,提出了粘聚力、内摩擦角与含水量的关系表达式.

| Abstract: | The shear strength characteristics of Lanzhou's loess with different shearing inclinations and different water contents were investigated experimentally and in different manner.Based on the tri-axial test results,the influence of water content and shearing bearings on Lanzhou's loess shear strength parameters.The results showed that the cohesion and friction angle of intact loess was not a constant but a variable with the cohesion and friction angle,so that the influence origin was interpreted.The dependence of cohesion and friction angle on the water content was presented,also. |
