| 摘 要： | 运用非线性破坏准则对边坡稳定性进行分析时需考虑的变量比线性情况多.基于非线性Mohr-Coulomb破坏准则,在考虑坡顶条形基础附属荷载情况下对边坡的稳定性进行了分析,采用极限分析原理对边坡的高度表达式进行了推导,并结合序列二次规划算法进行计算.再根据计算方法对工程实例进行计算,将结果与已有研究结果相比较,验证了该计算方法的正确性.

| Abstract: | It is necessary to consider more variables to analyze slope stability by using nonlinear failure criterion compared to the linear case. Based on nonlinear Mohr - Coulomb failure criterion, affiliated load of the crest strip foundation is considered to analyze the slope stability. Slope height expressions are deduced by the principle of limit analysis, and they are calculated with sequential quadratic pro- gramming algorithm. Then the paper calculates the engineering practice with the calculation method, and the results are compared with those of previous studies to verify the correctness of the calculation method . |
