摘要
探讨一种土钉支护边坡稳定分析方法，为设计提供较为科学合理的分析手段。基于双线性滑移面稳定分析方法，考虑土钉的极限拉力作用，建立稳定安全系数公式，用单纯形法求算最不利滑移面，并进行了工程实例计算，结果合理。
A method of stability analysis for soil nailing in excavation is investigated,sothat it may be applied in design and construction. A Safety factor formula of stability for soilnailed slope is set up,which tooks account of the limit tension of nail,based on the doublelinear method of slope stability analysis. The critical slip surface is searched by computer programming on the basis of a simplex method. Several engineering cases are analyzed and theresults are reasonable. The method is of practical use in engineering.
