为了计算刚性抗滑桩稳定性可靠度指标及失效概率,首先建立了抗滑桩锚固段内桩侧土体受压稳定性的功能函数,然后引入验算点法(JC 法)对失效模式进行计算,得出了可靠度指标和相应的失效概率.通过实例对比了JC法与安全系数法计算结果,结果表明,在安全系数满足要求的条件下,失效概率仍偏高,故在抗滑桩的设计计算中有必要引入可靠度理论.

In order to calculate the reliability index and failure probability for the stability of rigid anti-sliding pile, performance function was set for the stability of soil body suffering pressure at the side of anchoring section of anti-sliding pile, and JC method was introduced to calculate the failure mode, obtaining reliability index and failure probability. After comparing results from JC method and that from safe coefficient method, it is found that on the occasion of safe coefficient meeting requirement, failure probability is still higher. Consequently, it is necessary to introduce reliability theory into calculation during the design of anti-sliding pile.
