摘要
将有限元强度折减法(FEM-SSR)应用于边坡的稳定可靠性分析。文中提出了近似Monte Carlo模拟法、联合点估计法(PEM)对边坡进行稳定可靠性分析,得出了相应的稳定系数、可靠性指标和破坏概率,并与传统的基于极限平衡方法的可靠性计算结果进行了对比。结果表明:有限元强度折减法进行边坡稳定可靠性分析,其结果更接近坡体的实际稳定状态,在理论上和工程实践中均显示出一定优势。
Strength reduction finite element method（FEM-SSR） is applied in slope stability analysis.This paper puts forward pseudo Monte Carlo simulation method and joint point estimation method（PEM） to analyze slope stability.The corresponding stability factor,reliability indicator and failure probability are obtained and compared to the reliable result from traditional limit equilibrium method.It is shown that slope stability result using strength reduction finite element method is closer to the actual stabilized state and has a certain advantage in theory and engineering practice.
