| 摘 要： | 遗传算法是一种模拟生物进化过程的一种全优化算法,基于遗传算法的滑坡整体稳定性分析方法,以滑坡的稳定系数为目标函数,随机选择边坡中的N个滑面为初始种群,以滑面的圆心坐标和半径作为变量,模拟生物进化过程,按优胜劣汰机制搜索滑坡中稳定系数最小的滑面。将此方法用于分析四面山滑坡整体稳定性,并对照传递系数法计算值,验证了该方法在分析土层复杂的非均质滑坡中具有更高可信度。

| Abstract: | Genetic algorithm is a kind of fully optimized algorithm to simulate the process of biological evolution.The landslide global stability analysis is based on genetic algorithm,in which landslide stability coefficients are taken as the objective functions;N slides of slope are selected stochastically as initial population,and center coordinates and radius of the slide are taken as variants to simulate the process of biological evolution.The slide with minimum stability coefficients is searched out by the surv... |
