摘　　要：基于对曹妃甸港区新近吹填厚粉细砂层工程地质条件的分析,提出在场地地基加固中采用无填料振冲法处理工艺的方案。根据地基加固工程实施情况的监测和分析,总结无填料振冲法地基处理工艺的适用条件和优缺点,可供类似工程参考和借鉴。By analyzing geological condition of thick silty-fine-sand newly dredged to Caofeidian harbor, it is proposed to apply vibroflotation without backfill materials to foundation reinforcement. Then the foundation reinforcement construction is supervised and analyzed in order to summarize the suitability of vibroflotation without backfill materials as well as its merits and demerits, which will provide references for similar projects.
