卵形塔体钢连桥施工技术

摘要

Galaxy SOHO Center project is composed of four oval tower buildings which are mutually connected by 7 connecting bridges into a fantastic building cluster. At the lower part, the connecting bridge is high and has wide span, causing big installation difficulty. Key techniques and measures of wide-span steel connecting bridge, such as installation, measurement, welding, supporting system design and unloading, etc., are analyzed to ensure construction period, construction safety and economic benefit of steel connecting bridges.%银河SOHO中心项目由4栋卵形塔体结构组成,通过7座连桥连接成为富有科幻色彩的群体建筑物,其低区钢连桥跨度大、高度高、安装难度大,通过重点分析大跨度钢连桥的安装、测量、焊接、支撑体系设计以及卸载方式等关键技术措施,确保了钢连桥的施工工期、施工安全性及经济效益.
