中文摘要：
提出了一种边坡稳定计算的新方法，该方法采用Marc有限元软件计算边坡的应力。考虑了几何和材料非线性．采用一条折线模拟边坡滑动面．根据遗传算法原理编制程序，搜索对应最小安全系数折线上的节点，从而确定最危险的滑动面．与通常的边坡稳定计算方法相比，该方法摈弃了圆弧滑动面的假定并考虑了边坡的应力分布，可以更好地反映实际情况．算例比较表明，该方法计算结果更为合理．
英文摘要：
A method for slope stability calculation was introduced. FEM software Marc was adopted to calculate the stress on the slope, and geometrical non-linearity and material non-linearity were considered. The slip surface was simulated with a broken line. The program was composed based on genetic algorithm. It searched the nodes on the broken line with the minimum safety factor, and the most dangerous slip surface was found. Compared with traditional methods for slope stability, this method abandons the assumption of circular slip surface, takes into account the stress of the slope, and can better simulate actual condition. Comparison of the calculations shows that the results of the new method are more reasonable.
