摘要

岩石边坡开挖中存在大量的随机结构面，结构面与岩桥的组合破坏是边坡破坏的一种重要形式。如何确定抗剪强度最小的滑裂面是边坡工程中的重要研究方向。在岩体结构面调查统计基础上，运用随机网络模拟的方法得到边坡的裂隙网络图像，在此基础上应用模拟退火算法，搜索出边坡由结构面与岩桥组合形成的潜在最危险滑裂面的位置，将结构面组合滑动面与Sarma分析方法结合，形成一种改进的分析岩石边坡稳定性的方法——Sarma-SA分析法，通过一工程实例验证了该方法的合理性。

Abstract

There are lots of discontinuities whose geometry exhibits a random behavior in rock excavated slopes

and the failure surface of the slope is normally consisted of the joints and rock-bridges. To determine the lowest shear strength of the slope failure surface becomes the most important subject in slope engineering. Based on field investigation and statistic of the joints and Monte-Carlo simulation method

the joint mapping of the slope rock mass was determined. Then

the sliding surface of the slope can be determined by using the simulated annealing method and the stability factor of the slope can be calculated via a new improved two dimensional Sarma’s limit equilibrium method. A practical example was given to verify this method.
