CFG桩复合地基在高速铁路软土地基处理中的应用

Application of CFG Pile Composite Foundation in the Soft Soil Foundation of High-speed Railway

结合我国南方某软土地基工程特点,通过方案比选,确定了使用CFG桩复合地基施工方案,详细介绍了其施工工艺及注意事项,并对CFG桩复合地基应用效果进行了检验。检验结果表明,CFG桩复合地基施工方便、效果突出。

Combined with the characters of a soft soil foundation engineering in south of China, a CFG pile composite foundation construction scheme for the engineering is determined by comparing with some construction schemes of soil foundations. The construction processes of the scheme and points for attention during the construction are introduced in detail. And application effects of CFG pile composite foundation are inspected. The results indicate that the construction process of CFG pile composite foundation is simple and its effect is prominent.
