本文针对边坡抗滑桩锚固深度,构建刚性抗滑桩锚固深度的可靠性分析模型,选取Fiessler可靠指标法进行研究,把计算涉及的参数当作随机变量进行抗滑桩锚固深度的研究。工程算例表明,可靠指标随锚固深度的增加而提高,随地基系数、重度、比例系数及粘聚力等参数变异性的增大而减小,采用Fiessler可靠指标法进行抗滑桩锚固设计更符合实际情况,具有一定的参考意义。 In this paper, aiming at the anchorage depth of anti-slide piles in slope and the reliability analysis model for constructing anti-slide pile anchorage depth, the reliability index method of Fiessler is adopted to study the anchorage depth of anti-slide pile with random variables. The engineering examples show that the reliability index increases with the increase of anchorage depth and decreases with the variability of parameters such as foundation coefficient, severity, proportion coefficient and cohesion, and the Fiessler reliability index method is more effective for anti-slide pile anchorage design In line with the actual situation, has a certain reference value.
