| 摘 要： | 提出了基于粒子群算法（PSO）和最小二乘支持向量机（LSSVM）的边坡稳定性评价方法。该模型既利用了最小二乘支持向量机求解速度快、易于描述非线性关系的优良特性，同时也利用了粒子群算法快速全局优化的特点。粒子群算法用于搜索最小二乘支持向量机模型的最优参数，然后将模型用于预测边坡的安全系数。计算结果表明，该方法是合理的、有效的。

| Abstract: | A slope stability evaluation method based on particle swarm optimization (PSO) and least square support vector machine (LSSVM) is proposed. The method not only has the excellent characteristics of solving speed fast and describing nonlinear relationship easily of LSSVM, but also has the characteristic of fast global optimization of PSO. PSO is used to search the optimum parameters of LSSVM; then the optimal model is applied to predict the slope safety factor. The results show that the method is reasonable and feasible. |
