钻孔桩承载力试验分析及孔底虚土处理方法探讨

Experimental analysis of the bearing capacity on bored pile and disposal method of porous earth in the bottom of the bored hole

通过对50个单项工程的116根钻孔灌注桩的试验分析,提出了孔底虚土处理方法,对桩侧摩阻力及桩端阻力进行了讨论。

This paper analysed the results of load test on 116 bored piles in individual engineering, puts forward the disposal method of porous earth in the bottom of the bored hole and discusses the side frictioned force and tip resistance of pile.
