以红、黄两种不同颜色的滑带土为对象,采用室内试验,先对两种颜色的滑带土的基本物理力学性质进行测定,然后以力学性质较差的红色滑带土作为夹层,运用正交设计,研究夹层土的厚度、含水率等对滑带土强度参数内摩擦角()和粘聚力(c)的影响。实验结果显示,夹层土的含水率对滑带土强度参数内摩擦角()和粘聚力(c)影响最大,夹层土的厚度对强度参数也有一定的影响。 Taking red and yellow landslide soils as objects, indoor tests were conducted to determine the basic physical and mechanical properties of the landslide soils of two colors. Then the red slip zone soil with poor mechanical properties was used as the interlayer, Orthogonal design was used to study the influence of the thickness and water content of the interlayer soil on the internal friction angle () and cohesion (c) of the soil strength parameters. The experimental results show that the moisture content of interlayer soil has the greatest influence on the internal friction angle () and cohesion (c) of slip-soil strength parameters, and the thickness of interlayer soil has some influence on the strength parameters.
