摘要
CFG桩是一种针对软土路基施工建设的有效施工工艺,对软土路基处置具有良好效果。该文以某高铁工程为例,对CFG桩加固软土层的基本原理进行叙述,从长螺旋钻孔施工工艺、桩帽施工等关键环节对CFG桩施工工艺流程进行探讨,并针对性地提出CFG桩施工的关键要点和注意事项。该文旨在为类似工程施工的优化设计提供参考。
CFG pile is an effective construction technology for soft soil subgrade construction,which has good effect on soft soil subgrade disposal.Taking a high-speed railway project as an example,this paper describes the basic principle of CFG pile strengthening soft soil layer,discusses the construction process of CFG pile from the key links such as long spiral drilling construction technology and pile cap construction,and puts forward the key points and matters needing attention of CFG pile construction.This paper aims to provide reference for the optimization design of similar engineering construction.
