摘要:根据对78根钻孔桩和128根打入桩的统计分析,并使用校准法对现有钻孔桩和打入桩的抗力分项系数 进行了研究,结果表明,总抗力的分项系数受分布类型影响较大。文中提出由递推法分层土模型计算分抗力分 项系数,物理概念明确计算方法合理,结果可信。Abstract:According to the statistics of resistance in 78 bored piles and 128 drilled piles, the resistance partial coefficients of the bored piles and drilled 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 method have clear physical concepts. The calculation method is reasonable and the obtained results are credible.
