摘要

岩质边坡的失稳大都是沿各软弱结构面而发生的，其滑动面往往是软弱结构面的组合，呈阶梯状。岩石边坡中存在大量的随机结构面，从中找出抗剪力最小的滑裂面是边坡工程中的一个研究方向。在岩体结构面调查统计的基础上，用随机网络模拟再现结构面的空间分布，在此基础上应用A*算法，搜索出岩石边坡的临界滑裂面，并对临界滑裂面上的边坡体任意斜条分，与Sarma分析方法相结合，形成一种改进的分析岩石边坡稳定性的方法—— Sarma-A*分析法，通过工程实例验证该方法的合理性。

Abstract

A lot of landslides proved that: wreck of rock slope takes place along the joint

its slip surface always is the joint combination and is ladder shape. There are a lot of random joints in rock slope

finding out the slip surface whose shearing strength is minimum is a study direction of slope engineering. Based on investigating and statistics of joint

applying random network stimulation to reappearance space distribution of joints

and applying A* method to find out critical slip surface of rock slope; then separating slope above the critical slip surface slanting

combining with Sarma analysis method

come into being advanced rock slope stability analysis method-Sarma-A* method; and its rationality is validated by engineering instance.
