CFG桩复合地基的设计与施工

On design and construction of CFG composite pile foundation

从CFG桩的材料组成、布桩原则、直径及持力层的选择等多方面阐述了CFG桩的设计要点,并介绍了其具有易于操作、处理后复合地基承载力高、造价低等特点,提出CFG桩施工及验收的要求,以使该地基处理方法在工程实践中更广泛的应用。

From the material composition of CFG pile,the pile layout principle,the diameter and the selection of the bearing layer,the paper indicates some design points for CFG pile,introduces that it can be operated easily with high bearing capacity and low costs for the composite foundation,and points out the requirements for CFG pile s construction and inspection,so as to extend its application in engineering practice.
