摘　　要：结合某度假村项目酒店地基处理工程,设定了地基处理目标,采用了强夯法+CFG桩复合地基进行分区处理,探讨了地基处理设计方案。通过点夯夯沉量观测、地表平均沉降量观测、工后沉降观测、标准贯入试验、重型动力触探试验、平板载荷试验分析,表明强夯法+CFG桩复合地基处理厚层松散砂土地基具有良好效果,可供该区域类似工程参考。Based on the ground treatment of a hotel project in Sanya,the goal of ground treatment is set,the dynamic consolidation+CFG pile composite foundation is adopted,and the design is discussed by ground treatment.Through the data analysis of tamping settlement monitoring,surface settlement monitoring,post-construction settlement monitoring,standard penetration test,heavy dynamic probe test and plate loading test,the results show that thick loose sand ground by dynamic consolidation+CFG pile composite foundation has good effect,which provides reference for similar projects in Haitang Bay.
