摘　　要：PC工法组合钢管桩是一种钢管桩与拉森钢板桩连接的新型组合式围护桩。本文结合PC工法组合钢管桩在某大面积软土浅基坑中的应用实例,总结出PC工法组合钢管桩具有施工速度快、对环境影响小、占地空间小、可回收、经济效益好等优点。同时采用了同济启明星深基坑设计计算软件及Plaxis岩土有限元分析软件,对PC工法组合钢管桩结合一道钢管斜支撑支护典型剖面进行了计算分析,并与基坑实测数据进行了比较。The PC construction method composite steel pipe pile is a new type of composite enclosure pile that connects the steel pipe pile and the Larsen steel sheet pile.In this paper,combined with the application examples of PC construction method composite steel pipe piles in a large area of soft soil shallow foundation pit,it is concluded that the PC construction method composite steel pipe piles have fast construction speed,small environmental impact,small footprint,recyclability,and economic benefits.Good to wait for the advantages.At the same time,the Tongji Qimingxing deep foundation pit design and calculation software and the Plaxis geotechnical finite element analysis software are used to calculate and analyze the typical section of the PC construction method combined steel pipe pile combined with a steel pipe oblique support,and carry out the calculation with the measured data of the foundation pit Comparison.
