【摘要】 论述了边坡含主控弱面的双滑块玻坏形式之可靠度计算方法，同时研究了利用优化方法来搜寻最小可靠度下的最危险滑面．将此边坡可靠度优化分析法应用于新疆雅满苏铁矿东采场下盘边坡可靠度分析，获得了成功．该法可用于评价各类双滑块破坏边坡的可靠性．更多还原

【Abstract】 The paper describes the optimical reliability analysis method of rock slope existing decisive joints in double--block failure pattern, and discusses how to search for the critical failure surface by using of optimical method. The method is successfully applied to analyse the slope stability of Yamasu Iron Mine, and can also be used to evaluate the slope reliability of various double-block failure pattern.更多还原
