摘　　要：以城市环境复杂区域某深基坑工程为依托,采用深基坑顺逆结合施工方法,创新配套的“单桩单柱”格构柱精准施工、外包竖向柱施工、多层结构柱竖向钢筋连接等构件节点施工技术,并研制了一种梁板施工悬挂支撑体系,保障了基坑工程整体支护效果,且环保经济。Based on a deep foundation excavation project in an urban area with a complex environment,the combined forward and reverse construction method of a deep foundation excavation is adopted.The construction technology of component nodes,such as precise construction of a“single pile single column”lattice column,outsourcing vertical column construction and vertical reinforcement connection of multi⁃layer structural columns,etc.,is innovated.And a suspension support system for beam and plate construction,which is both environmentally friendly and economical,is developed to ensure the overall support effect of foundation excavation engineering.
