| 摘 要： | 根据Bishop简化法的计算假定和原则,并假定边坡的整体滑动方向,推导出三维边坡稳定分析的计算方法。该方法适用于对称和非对称的旋转破坏的边坡稳定问题,如边坡破坏面为对称的圆弧、旋转椭圆等旋转面,或者这些旋转面的组合面,或者旋转面与平面的组合面等。探讨了三维Bishop简化法应用于非对称破坏存在的问题。

| Abstract: | Three dimensional slope stability analysis with limit equilibrium method is developed, based on the assumption used in Bishop’s two dimensional simplified method. The sliding direction of whole slope is assumed. Thus this method can be applied to slope with rotational failure surface such as semispherical, ellipsoid, or composite failure surface that is the combination of the above rotational surface with plane.In this paper, some problem of applying this method to asymmetric slope is discussed. |
