摘要
边坡稳定分析Sarma法,先计算力的平衡,再通过每个分条力矩的平衡来检验所求稳定系数的正确性。但现有的电算程序,有的未进行力矩平衡检验,有的检验过程中li和Zi组合不全,从而影响计算结果的正确性。本文对此进行了分析,并以具体块段为实例剖析了现有验算方法的不足,综合全面地考虑了块体平衡的所有可能情况,提出了改进方法,弥补了原方法中的不足。
In sarma method for slope stability analysis,the calculation on force balance is done,followed by checking the correctness of calculated stability coefficient by the moment balance of all slices.However,it has been found that there is no moment calculation in some computer programs, and the incomplete fit of l_i with Z_i in others can result in wrong conclusion.In this paper,the shortages of primary validating method are pointed out and an improved method in which all of possible slice balances are considered is put forward on the basis of analyzing a practical example.
