粉喷桩承载力统计及其可靠性分析

Statistical analysis and reliability of DJM pile bearing capacity

依据邯郸市区粉喷桩承载力设计以及试验检测的实际情况,抽取一定数量的粉喷桩承载力试验检测值与其相应的设计值进行比较,对其比值(试计比)进行归一化分析,并在此基础上对该地区粉喷桩承载力的可靠性进行了简要的计算,给出了试计比的分布类型及各工况下的可靠性指标,为邯郸市区粉喷桩设计作了有益的探索。

On the basis of the fact of DJM pile ultimate bearing capacity and dead - load experiment in Handan, including the information of test and design value, this paper analyses a statistic model for the ratio of test data to design data basing on the fact of design about DJM pile ultimate bearing capacity and dead - load experiment. It also obtains the reliability index and role of probability distribution about DJM pile ultimate bearing capacity in Handan. Through calculation of the reliability index , the availability of the method is verified.
