2 概率分析
这个报告题目为"A probabilistic-based approach to rock slope stability analysis in open-pit mine using numerical modelling(基于概率的露天矿岩石边坡稳定性分析---采用数值模拟法)", 报告人来自南非约翰内斯堡大学(University of Johannesburg)。
我们的边坡稳定性分析方法已经发生了巨大变化。(1) 由确定性分析全面转到概率分析; (2) 非圆形滑动面取代了圆形滑动面;(3) 全局优化进化到局部优化;(4) 三维分析代替了二维分析;(5) 破坏概率代替了安全系数;(6) 增加了岩土的空间变异性分析;(7) LEM与FEM高度集成。
