| 摘 要： | 基于有限元折减法的原理进行了三维边坡模型的稳定性分析。结果表明:当三维边坡模型可简化为二维边坡模型时,三维和二维计算的差别不大,适合采用M-C等面积准则进行分析,不同判断失稳的标准会影响结果,以收敛为判断标准满足一定精度要求。当用三维空间模型计算时,假设滑动面和不假设滑动面的计算结果有偏差。

| Abstract: | This paper carries out analysis on the stability of three-dimensional slope model based on the principle of strength reduction finite element method.The result indicates that if three-dimensional slope model can be simplified to two-dimensional,the calculation between them has little difference and it is suitable to carry out analysis with M-C equal-area rule.Different standards for stability loss will influence the result,so convergence criterion is applied to satisfy a certain precision.For three-dimensio... |
