摘要
通过对 12 8根现场打入桩的整理分析 ,利用桩的可靠性原理 ,采用“校准法”对现有打入桩的抗力分项系数进行了研究。结果表明 :打入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 128 driven piles, and utilizing the reliability principle on piles, the resistance partial coefficients of the driven 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 simply and reasonable method.
