摘要
通过对比47根钻孔桩静力触探和静载荷试验资料,对钻孔桩承载力的无量纲随机变量试计比λp作了统计分析,检验了其分布特性,考虑了土性的空间自相关性,并用核准法对现有静力触探公式设计的轴力桩的可靠指标进行了计算。
By comparing the testing data of static cone penetration tes(CPT)and static load test of 47 bored piles, the ratioλP of the dimensinless stochastic variable of bored pile bearing capacity is statisitcally analyzed and the distributioncharacterstics are examined in the paper. Considering the spatial correlation of soil properties, using calibration method,the reliability index of axially loaded pile bearing capacity desinged from the available CPT formulae is ealculated.
