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.

Key words: joint, A* method, Sarma analysis method, Sarma-A*
