摘要
边坡临界滑面的确定是边坡稳定性分析的关键,对于非圆弧滑动的非均质边坡而言,已有的各种分析方法往往过于繁琐,不便于工程推广。本文基于传统的Sarma法,应用MicrosoftExcel电子表及其非线性规划求解工具,以实例给出了电子表法确定边坡临界滑面的实现方法。该法简便明了,具有较大的工程应用价值。
The key of analysis on slope stability is the determination of the critical failure surface. As for nonhomogeneous slopes sliding with noncircular failure surface, the existing methods are often too complex to extend in engineering. Based on the traditional method of Sarma,this paper provides a realizable method-spreadsheet method for determining the critical surface of slopes with an example.The method is proved to be brief and clear. It is worth being applied in geotechnical engineering.
