摘要
通过邯郸市某大厦CFG桩试验桩的施工及检测过程,介绍了该工程CFG桩试验桩缺陷形成的原因、对单桩承载力的影响程度及施工工艺的改进方案,载荷试验表明,施工工艺改进后单桩承载力得到了大幅度的提高,也能有效地解决CFG桩在施工过程中出现的施工质量问题。
Through the constructing and detecting process of CFG testing pile in the building of Handan,this paper introduces the reasons of generating construction quality defect,the influence on the bearing capacity of single pile and the technical project improved,and shows the bearing capacity of single pile is improved greatly afterward measures improved.This case indicates construction quality defect can be effectively settled by upgrading construction technology considering engineering geological property.
