摘　　要：针对深基坑稳定分析,提出了用等弧长条分法来确定深基坑最危险滑动面及其相应的最小稳定系数,通过工程实例验证了该方法有效,且应用便利.The most dangerous sliding surface and the corresponding minimum stability coefficient of the deep excavations can be determined by using Equa-Arc algorithm. Based on the assumption of circular sliding surface, a forward formula for deep excavations stability has been derived according to the equal-arc method. The effectiveness of the suggested method is proved by an engineering project.
