南昌地区典型厚密砂层PHC管桩施工技术研究
摘要:依托南昌地区某桩基工程，采用静力触探原位试验分析该地区典型厚密砂层地质特征，结合理论计算及现场试验分析PHC管桩的锤击沉桩阻力及设计单桩极限承载力，对工程桩的设计及施工提出合理建议，同时总结该地层条件下锤击PHC管桩成桩的施工工艺。后续工程桩承载力检测结果表明，优化调整后的施工技术满足了工程设计要求，取得了良好的社会与经济效益，可在该区域推广应用。
Abstract:Based on the example of pile foundation in Nanchang, static penetration in-situ test was used to analyze the geological characteristics of typical thick-dense sand layers in the area. Based on theoretical calculations and on-site tests, the hammer sinking resistance of PHC pipe piles and the ultimate bearing capacity of a single pile were analyzed. Reasonable suggestions were proposed for the design and construction of engineering piles, and the construction process of hammer driving PHC pipe piles under this geological condition was summarized. The subsequent pile bearing capacity testing results show that the optimized and adjusted construction technology meets the engineering design requirements and has achieved good social and economic benefits, which can be promoted and applied in this area.
