为了对抗滑桩锚固深度进行合理的设计,建立位移迭代有限元模型模拟桩-土间的相互作用,基于强度折减的位移迭代有限元法对边坡抗滑桩加固工程进行可靠性分析,把计算参数视为随机变量考虑参数变异性对抗滑桩锚固深度及边坡加固工程可靠性的影响。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。工程算例表明采用可靠性方法设计抗滑桩锚固深度是合理的,具有一定的工程应用价值。

To rational design the anchorage depth for rigid anti-slide piles,a calculated method of interaction process of the pile-soil is presented in this paper： the displacement iterative finite element method,research on reliability of slope reinforced by anti-slide piles based on the method of strength reduction theory with displacement iterative finite element method,the calculated parameters are regarded as random variables when considering the different values of random variable impact on the reliability of anchoring depth for anti-slide piles and reinforced slope.The classification of a slope project should be considered in selecting the reliability index,the target reliability as control index to guide the design for the anchoring depth of anti-slide.Examples show that the reliability analysis to design the anchorage depth of anti-slide piles is rational and useful for engineering applications.
