| 摘 要： | 基于SMP(Spatially Mobilized Plane)屈服准则,即考虑中间主应力对土体边坡稳定的影响,分析了边坡土体三维应力状态下的应力和抗剪强度问题,并建立了土体边坡稳定安全系数计算公式。并将该方法计算结果与目前常用的Mohr-coulomb强度准则等方法考虑土体边坡稳定性进行比较,表明采用该方法更加符合实际情况。

| Abstract: | Based on the SMP(Spatially Mobilized Plane) criterion,this article analyzes the problems of soil stress and shear strength in state of three-dimensional stress,and compares the result with the Mohr-coulomb criterion and then establishes the corresponding relationship between them.On the basis of the SMP strength criterion,the paper considered the influence on the principal stress in the soil and revised the formula of calculating slope stability.Compared the calculation results with the Swedish circle method,it is shown that using this article’s formula calculates the slope’s factor is smaller. |
