摘　　要：在苏南软土地区,深基坑工程通常采用围护桩(墙)+内支撑的基坑支护设计形式,其中相对于常规支护设计,采用一道组合型钢支撑+SMW工法桩的支护体系具有更好的经济性、工程性和施工便利性,通过对无锡某个深基坑项目实际应用情况分析,证明了该类支护体系的可靠性,可为今后同类型项目积累工程经验。In the soft soil area of southern Jiangsu,deep foundation pit engineering usually adopts the design form of retaining piles(walls)with internal support for foundation pit support.Compared with conventional support design,the support system using a combination of steel support and SMW construction method piles has better economic,engineering,and construction convenience.This paper analyzes the deformation law of a deep foundation pit project in Wuxi proves the reliability of this type of support system,accumulating engineering experience for similar projects in the future.
