边坡稳定性分析的改进条分法

边坡稳定性分析的改进条分法 English Version

摘要: 本文利用极限分析和刚性有限元离散概念￣［１１］，提出了一种用于边坡稳定性分析的改进条分法。该方法利用优化技术直接调整条块间及滑裂面上的内力，使得对给定的滑裂面安全系数取最大值，而对各个不同的滑裂面寻求使安全系数为最小的滑裂面。对滑裂面的形状、条块间的内力之间的关系等不做任何假定，因此能更真实地反映边坡的实际稳定状态。

Abstract: By adapting the idea of limit analysis and finite element analysis an improved slice method for slope stability analysis is proposed. The internal forces on slip surfaces are adjusted through optimiza- tion so that the safety factor is maximized for any given slip surface. The real satety factor should be the minimum one among these possible slip surfaces.This method doesn’t introduce any assumption about the internal forces on slip suriaces,so it can be used to estimate the true stability of slope.
