| 摘 要： | 基于极限分析的上限理论，对非线性破坏准则的边坡稳定性问题，提出了一个线性简化方法。该方法把复杂的非线性问题化成线性问题，从而在实际工程应用时，可以利用已有的关于线性问题的分析结果或根据本论述的方法使问题简化。数值算例表明了该方法的简单实用性。

| Abstract: | Based on the upper bound method of limit analysis, a method is suggested, which converts the slope stability problem with a nonlinear failure criterion to one with a linear criterion. Comparison of the numerical results by the linear method suggested here with those obtained by using a nonlinear failure criterion available in the literature shows that this simple method is satisfactory for engineering practice. |
