| 摘 要： | 建立了边坡稳定性分析的平面直角坐标系,得到了该坐标系下的边坡稳定分析瑞典圆弧法的积分表达式。以简单均质粘性土坡为研究对象,结合MATLAB遗传算法工具箱,建立了基于瑞典圆弧法的遗传算法优化模型,实现了边坡稳定分析最小安全系数的自动寻优。通过实例进行验证和对比,表明该方法是行之有效的。

| Abstract: | A plane Right-angle coordinates for analysis of the stability of soil slopes is set up,and the integral formulae of the stability analysis based on the Sweden arc method are obtained under this coordinates for the simple homogeneous clay slope.A genetic algorithm optimization model based on the Swedish arc method was established by using the Genetic Algorithm and Direct Search Toolbox of MATLAB,which realized automatic optimization of the minimum safety factor of slope stability.An example is given and is c... |
