摘要
Abstract
Some of the rocky slopes with a great quantity of fractures haven't weak planes, so the position of the fracture distri-bution is the key to the stability of the slope. The estimation of safety slope angle is usually incorrect in practical work. The con-ventional estimation method of safety slope is to find out the preponderant combination of the fractures inside the slope and use the stereographic method to estimate the safety angle. According to the stability analysis on the basis of stochastic dynamics, the slid-ing direction of the most dangerous sliding surface is the inclination of the slope. Every fracture on the rock face is stochastic, which influence the stability of the slope. These fractures may result in single sliding surface destruction or form wedge stochasti-cally to cause the slope failure. The excavated slope of Donghuangliu Station of Dalian Port is taken for an example, the stochastic dynamics method and stereographic method are combined in the analysis to obtain the reasonable safety slope angle.关键词
