摘　　要：通用条分法是滑坡稳定性分析的常用方法之一,然而在实际应用中常存在迭代计算求解过程无法收敛的问题。选取某典型滑坡实例,对通用条分法迭代过程不收敛的成因进行剖析,并给出相应的解决方法,采用该方法处理后通用条分法计算过程很快得到收敛,证明该方法有效。The general slice method is a common method for landslide stability analysis.However,in practical applications,there is often a problem that the iterative calculation process cannot converge.A typical landslide example is selected to analyze the causes of the non-convergence of the iterative process of the general slice method,and the corresponding solutions are given.After this method is used,the calculation process of the general slice method is quickly converged,which proves that the method is effective.
