| 摘 要： | 研究了地震荷载作用下水平向成层边坡稳定性分析的计算方法。根据水平向成层边坡的特点，提出了适合此类边坡的水平条分法，并利用具有良好全局收敛性能的遗传算法对临界滑动面进行搜索．通过实例验证和与其他方法对比分析，结果表明这种方法不仅准确可靠，而且总能搜索到全局最优解。

| Abstract: | The computing method for the stability analysis of slopes composed of horizontal layers under seismic load is studied. According to the characteristics of such slopes,horizontal slice method (HSM) is developed and applied to search for the critical slip surface in combination with genetic algorithm (GA) which is of the capability of global convergence. The analysis results of some slopes by the proposed method and the comparisons between the proposed method and other ones show that the proposed method is accurate,reliable and able to find out the global optimal solution. |
