摘　　要：结合南宁市"三街两巷"项目,对新型静压钢板桩结合钢筋混凝土内支撑的深基坑支护施工技术进行了研究,重点阐述了钢板桩插拔、钢板桩与钢筋混凝土内支撑节点连接、内支撑拆除等关键施工技术。通过对施工重点工序的质量把控,确保了狭窄空间内深基坑的施工安全和周边建筑变形要求,可供类似工程参考。Combined with the project of"three streets and two alleys"in Nanning City,the paper studies the construction technology of deep foundation pit support with new static pressure steel sheet pile combined with reinforced concrete internal bracing,and focuses on the key constructio n tech no logies such as steel sheet pile insertion and removal,steel sheet pile and reinforced concrete internal bracing joint connection,and internal bracing removal.Through the quality control of key construction procedures,the construction safety of deep foundation pit in narrow space and the deformation requirements of surrounding buildings are ensured,which can be used as a reference for similar projects.
