摘要
通过对78根现场钻孔灌注试桩的整理分析,利用桩的可靠性原理,采用“校准法”对现有钻孔灌注桩的抗力分项系数进行了研究。结果表明:钻孔灌注桩总抗力分项系数的分布类型对其值影响较大,由递推法计算桩的分层土模型的抗力分项系数是一种简便、合理的方法。
According to the statistics of resistance in 78 bored piles, utilizing the reliability principle on piles, the resistance partial coefficients of the bored piles are studied using calibration method. Results show that the partial coefficient of the main resistance is affected greatly by its distribution type. The partial coefficients of resistance obtained by recurrence analysis is a type of simply and reasonable method.
