水泥粉煤灰CFG桩(CFG桩)已成为地基处理中应用较为普遍的技术之一,桩基作为一个工程的隐蔽工程,施工质量的好坏,不仅关系到一个工程的成败,而且涉及到千家万户的利益,大多数的研究都集中在其工作机理和理论分析的研究上,很少有关于CFG桩的施工方面的研究,实际中的CFG桩的施工质量由于操作不规范,缺乏施工知识的指导,导致了存在非常大的问题,从而严重影响了CFG桩的强度等因素,使得实际的桩体和设计要求相差甚远。因此,有必要着重研究一下CFG桩的施工问题。
Cement fly ash CFG pile (CFG pile) has become one of the most commonly used techniques in foundation treatment. As a hidden engineering of pile foundation, the quality of construction is not only related to the success or failure of a project, but also to thousands of Most of the research interests focus on their working mechanism and theoretical analysis. There are few studies on the construction of CFG piles. The actual construction quality of CFG piles is lack of construction knowledge due to non-standard operation , Leading to the existence of very large problems, which seriously affected the strength of CFG piles and other factors, making the actual pile and design requirements far apart. Therefore, it is necessary to focus on the CFG pile construction problems.
