摘要
分析了某新建高速公路路基试验段CFG桩基质量检测的数据,总结出浅层断桩和缩径是CFG桩最主要的质量缺陷,分析了造成此类缺陷的主要因素,并从人员管理、掺入早强剂、优化施工顺序、控制提管速度、设置保护桩长等几个方面提出了防治措施。
Analysis the detection data of CFG pile of a certain new soft soil roadbed,summary to the piles broken at shallow level and diameter shrinkage is the most important quality defect,and analysis the key factors,from five aspects to assure the quality of CFG pile,such as reinforce educating workers,adding early strength agent,optimizing the order of construction,controlling the speed of lift pipe,setting protection pile.
