| 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. |
| Keywords: | joint A* method Sarma analysis method Sarma-A* |
