摘要
针对现有边坡三维极限平衡分析方法,提出了一种对称破坏机制下的边坡稳定三维滑动场分析方法,该方法基于剩余推力法原理,采用优化控制理论求解危险滑面并进行评价.同时,结合矿山人工开挖边坡的特点,应用三维滑动场方法进行反向搜索,即在指定安全系数下计算最大允许坡角,从而实现边坡优化设计.
This paper suggests a slope stability three-dimensional critical slip field analytical method based on symmetrical destructive mechanism relative to the existing three-dimensional slope stability analytical approach. The method is based on the residual thrust theory, and uses the opti- mization control theory for the construction of the critical slip field. Meanwhile, the method can be used for backward search combined with the special features of manual excavation of the side slope, which means figuring out the maximum allowable angle under a given safety coefficient, to achieve the optimum design of the slope.
