粉喷桩竖向极限承载力概型分布研究

Research on probability distribution of ultimate bearing capacity of DJM pile

基于静载荷试桩资料,通过对邯郸地区12个粉喷桩工程中每个工程的单桩极限承载力特征参数的统计分析,阐明了邯郸地区粉喷桩单桩极限承载力基本服从于对数正态分布。可供进行该地区粉喷桩单桩承载力可靠度分析时参考。

<Abstrcat>Based on the data of static load test, the statistic analysis of the characteristic parameter of the single DJMP's ultimate bearing capacity was performed, from all of 12 practical projects with the DJMP technique in Handan. The results show that the single DJMP's ultimate bearing capacity belongs to logarithmic normal distribution. The conclusion is able to be used as a reference law in the reliability analysis about the single DJMP's ultimate bearing capacity in similar area.
