在分析比较各岩土体物理力学参数(包括抗剪强度参数、弹性模量、泊松比、剪胀角、抗拉强度)对均质土边坡稳定性及滑带的影响基础上,发现弹性参数和剪胀角、抗拉强度对边坡的稳定性影响较小,粘聚力和内摩擦角的影响较大,但各力学参数对滑动面的影响尚不足以改变土坡的整体破坏模式,同时得出坡角取34.5°是均质土坡中粘聚力和内摩擦角发挥作用程度相等时的临界坡角。
On the basis of analyzing and comparing the physical and mechanical parameters (including the shear strength parameters, elastic modulus, Poisson’s ratio, dilatancy angle and tensile strength) of rock and soil mass on the stability and sliding zone of homogeneous soil slope, The elastic parameters, dilatancy angle and tensile strength have little influence on slope stability and cohesion and internal friction angle, but the influence of mechanical parameters on the sliding surface is not enough to change the overall failure of the slope Mode. At the same time, it is concluded that the slope angle is 34.5 °, which is the critical slope angle when the cohesion and internal friction angle in homogeneous soil slope play an equal role.
