CFG桩复合地基施工质量控制

On the construction quality control of the CFG pile composite foundation

结合海南东环铁路CFG桩复合地基施工情况,阐述了复合地基与CFG桩的定义、CFG桩的加固机理及褥垫层的作用,提出了CFG桩的施工质量控制要点,通过质量控制措施的实施,极大地提高了软土地基的承载力,取得了良好的效果。

Combining the construction situation of the CFG pile composite foundation in Hainan Donghuan railway, the paper illustrates the definition of the composite foundation and CFG pile, the intensifying principle for the CFG pile, as well as the cushion, points out the control points for the construction quality of CFG pile. According to the implementation of the quality control, the loading capacity of the soft soil can be improve in a great way and the effect is good.
