摘要: 为合理采用边坡稳定性的概率分析方法,基于垂直条分极限平衡法SLIDE软件平台和斜坡软弱地基路堤离心模型试验结果,对全局最小方法和整体边坡方法的原理和计算结果进行了比较,并用整体边坡方法分析了抗滑桩加固对斜坡软弱地基路堤稳定性的影响.研究结果表明:与全局最小方法相比,整体边坡方法算法更严谨,计算结果更全面,设计更趋保守,但计算耗时较多,应根据模型复杂程度、分析目的等合理选择概率边坡稳定性分析方法;整体边坡方法能较好地从破坏概率的角度论证抗滑桩加固斜坡软弱地基路堤的科学性、有效性.Abstract: In order to reasonably select probabilistic slope stability analysis methods, a comparison research on the global minimum method and the overall slope method was carried out based on vertical slice limit equilibrium method software SLIDE and geotechnical centrifuge model test of embankment on sloped weak ground. The overall slope method was used to get the influence rule of anti-slide pile reinforcement on the stability of embankment on sloped weak ground. The research result shows that compared with the global minimum method, the overall slope method has a strict algorithm, more and conservative results, but more time consumption. The selection and application of the two probabilistic slope stability methods should depend on the model complexity and the analysis goals. The overall slope method can prove the effectiveness of anti-slide piles for embankment reinforcement on sloped weak ground well.
