摘　　要：水泥搅拌桩是利用水泥和软土搅拌强化成具有一定强度和水稳性的搅拌柱体,在软土地基处理实践中被广泛应用,具有施工简易、经济成本低,成桩质量高等优点。水闸基础坐落在深厚淤泥层中,地基基础软弱,基础承载力低,为了保证水闸工程安全运行,文章对水闸进行水泥搅拌桩复合地基基础处理,旨在提高地基承载力和控制水闸软土基础沉降变形,并进行桩体试桩试验以检测桩体强度、均匀性等指标,可为类似软土地区复合地基设计与试验提供科学参考。Cement mixing pile is a kind of mixing column with certain strength and water stability by mixing cement and soft soil,it is widely used in the practice of soft soil foundation treatment,and has the advantages of simple construction,low economic cost and high pile quality.The foundation of the sluice is located in the deep silt layer,the foundation foundation is weak and the foundation bearing capacity is low.In order to ensure the safe operation of the sluice project,the cement mixing pile composite foundation is treated for the sluice.The purpose is to improve the bearing capacity of the foundation and control the settlement deformation of the sluice soft soil foundation,and the pile test is carried out to test the strength and uniformity of the pile,which can provide scientific reference for the design and test of composite foundation in similar soft soil areas.
