摘　　要：为保证淮河干流息县枢纽节制闸振冲挤密砂桩复合地基满足设计要求,确保工程安全可靠运行,根据地基处理设计方案,针对节制闸地基特性,通过选取原状土地基和回填土地基进行现场试验,采取动力触探和标准贯入试验检测桩体和桩间土加固效果,确定了振冲挤密砂桩施工技术参数,明确了施工质量控制要点和关键环节,为类似工程积累了可靠的施工经验。In order to ensure that the composite foundation of vibroflotation sand compaction pile of regulating sluice of Xixian junction in the main stream of Huaihe River meets the design requirements and ensure the safe and reliable operation of the project, according to the design scheme of foundation treatment and the characteristics of the regulating sluice foundation, the in-situ test is carried out by selecting the undisturbed soil foundation and the backfill soil foundation. The dynamic penetration test and standard penetration test are adopted to detect the reinforcement effect of the pile body and the soil between piles. The construction technical parameters of vibroflotation compaction sand pile are determined, and the key points and key links of construction quality control are clarified, which has accumulated reliable construction experience for similar projects.
