三维边坡稳定性分析的一种适用方法

摘要

基于空间曲面上一点的应力关系、曲面至边坡表面土柱上力的微分平衡方程、力矩平衡方程,只需要一个假定条件,得出了一种广泛适用的三维边坡稳定性分析法,并讨论了方法应用中的有关问题.算例表明,该方法计算结果是合理的,具有广泛的应用意义.%Based on the stress relationship at a point on a curved spatial surface, and the differential equilibrium equations forforces and moment on the soil column from the curved spatial surface to the surface of a slope, an applicable method forstability analysis of three-dimensional slope is developed with only one hypothesis. Some problems in the application of thismethod are discussed. The calculated results show that the results are reasonable and the method is widely applicable.
