摘要
土坡稳定分析中的临界滑动面搜索需要以有效地模拟滑动面策略为前提。本文基于对常用策略的分析,提出了几种新策略以模拟任意滑动面,并利用和声搜索算法和Spencer法联合进行土坡稳定分析,将新策略以及常用策略应用于4个土坡的临界滑动面搜索中,比较了采用不同策略的搜索效率。计算结果表明:对于简单的均质土坡,不同策略的效率相差不大;而对于复杂土坡,应用本文提出的新策略则比应用常用策略的效率高,且该策略适用于含规则、不规则软弱夹层土坡的计算。
The procedures for effectively simulate the slip surfaces of soil slopes are vital to searching critical slip surface in stability analysis.In this paper,some new procedures for generating arbitrary slip surfaces are proposed and the harmony search algorithm is combined with Spencer method of slice to carry out the slope stability analysis.The comparison of the searching efficiency in stability analysis of four typical soil slopes shows that the proposed procedures are better than those current widely used ...
