摘　　要：介绍了超深水泥土搅拌桩在上海某工程应用的过程,对取自现场的芯样进行室内渗透试验,测定不同深度处桩体芯样的渗透系数,并进行统计分析。试验表明,采用超深水泥土搅拌桩能够显著降低砂性土层的渗透系数,可起到很好的隔水效果。This article presents the application process of extra-deep cement mixing pile in a project case in Shanghai.Laboratory test was made to study the permeability of the soil samples taken from the construction site.The test finds the permeability parameters of pile at different depth and makes the statistic analysis.The test results show that the extra-deep cement mixing pile can significantly reduce the permeability parameters of sandy soil layer so as to achieve a good water-stop effect.
