CFG桩质量通病分析及控制措施研究

CFG pile quality disease analysis and control measures research

结合工程实例,介绍了CFG桩复合地基的施工流程,从成孔及灌注混合料两方面,分析了CFG桩的质量通病,并提出了具体的控制措施,指出CFG桩与其他桩基相比造价较低,在建筑工程中应用前景广阔。

Combining with engineering example,the paper introduces construction procedures of CFG pile composite foundation,analyzes CFG pile quality diseases from two aspects of hole-forming and pouring mixture,and puts forward specific control measures. In the end,it points out that：comparing other pile foundations,CFG pile composite foundation has lower cost and will have wide application prospect in building engineering.
