摘要
将进化策略与边坡稳定极限平衡法相结合,建立了边坡任意形状最危险滑裂面及相应最小安全系数的全局优化搜索方法。该方法适用于任意几何形状、不同岩土材料分层以及多种荷载作用的复杂边坡。通过典型算例分析,证明应用进化策略搜索边坡任意形状最危险滑裂面是可行和高效的,并且具有较强的鲁棒性。
Based on the combination of evolution strategy and l imit equilibrium method, an effective global optimization method is proposed to allocate the most dangerous non-circular critical slip surface corresponding to the minimum factor of safety in slopes. The method can be applied to slopes wit h any configuration, different layering and external load distribution. The feas ibility, efficiency and robustness of the proposed method are finally demonstrat ed with the stability analysis of a classic slope case.
