摘　　要：滨海地区拦河闸地基多为软土,无法满足上部结构承载要求,需进行地基加固处理。结合珠江流域某拦河闸建设实际,由于闸室下部基础坐落于淤泥及松散粗砂土层,为提高地基承载力并控制闸室沉降变形,经技术经济比选后采用水泥搅拌桩复合地基方案。为确保复合地基质量满足要求,对施工质量采取控制措施。工程实践表明,水泥搅拌桩加固方案可满足各项设计指标,施工后的桩体符合国家相关规范验收要求。The foundation of river gates in coastal areas is mostly soft soil,which cannot meet the bearing requirements of the upper structure and requires foundation reinforcement treatment.The lower foundation of a sluice chamber in the the Pearl River basin is located in the silt and loose coarse sand soil layer.In order to improve the bearing capacity of the foundation and control the settlement and deformation of the gate chamber,the cement mixing pile composite foundation scheme is adopted after technical and economic comparison.To ensure that the quality of the composite foundation meets the requirements,control measures are taken for the construction quality.Engineering practice has shown that the cement mixing pile reinforcement scheme can meet various design indicators,and the pile body after construction meets the acceptance requirements of relevant national regulations.
