摘　　要：介绍了CFG桩的施工方法,分析了CFG桩的成桩质量,同时进行了CFG复合地基承载力试验。结果表明:CFG桩桩身连续,强度高,复合地基承载力满足设计要求,施工质量良好,保证了CFG桩复合地基的加固效果。采用CFG桩复合地基技术处理高速公路桥头深厚软土地基是一种有益的尝试。The CFG pile construction method was introduced. Quality of CFG pile was analyzed. The CFG complex base bearing test was carried on. The results showed that the CFG pile continuity and strength complex base bearing satisfied the design requirements. The construction quality was good and guarantees the CFG pile complex base effectiveness on strengthening. It was a beneficial attempt that the CFG pile compound base technology had been applicated in deep soil soft base treatment of highway bridge head.
