摘要

摘要: 为了确定刚性抗滑桩锚固深度，建立了锚固深度的可靠性分析模型，基于强度折减有限元法进行了可靠度分析；可靠指标的选取应考虑边坡工程等级，以目标可靠度为控制指标去指导抗滑桩锚固深度的设计。通过工程实例，把计算参数视为随机变量，以可靠度分析考虑参数变异的程度对抗滑桩锚固深度的影响；通过可靠指标对参数的敏感性分析确定抗滑桩锚固深度主要影响参数；算例表明采用可靠度分析方法确定抗滑桩锚固深度是合理的，具有一定的工程应用价值。

Abstract: To determine the anchorage depth for rigid anti-slide piles, a reliability analysis model is established based on the strength reduction finite element method. The target reliability index is selected according to the classification of slope engineering, and the design of the anchorage depth of anti-slide piles is guided by the target reliability index. Through the analysis of a practical project, the effects of the variation of soil layer parameters on the anchorage depth are studied. The main influence parameters are determined. It is shown that using the reliability analysis method to determine the anchorage depth for rigid anti-slide piles is rational and useful for engineering applications.
