摘要
本文针对既有城市交通系统复杂,存在新建桥梁与既有道路交叉多、施工环境复杂、施工难度增加等问题,鉴于钢箱梁跨度大、架设方便等优点,对跨越既有城市道路的钢箱梁整体吊装施工技术进行了研究,重点分析了吊装施工方案比选、钢箱梁节段分块设计、钢箱梁吊装施工技术,为存在交叉施工现象、城市道路交通流大等复杂施工环境的钢箱梁吊装施工提供指导和借鉴。
In view of the complicated traffic system in existing cities,there are many problems such as the bridge between newly built bridges and existing roads,complex construction environment and difficulty of construction.Considering the advantages of large span of steel box girder and convenient erection,the whole hoisting construction technology of the beam is studied.The comparison and selection of the hoisting construction scheme,the section block design of the steel box girder and the hoisting construction technology of the steel box girder are mainly analyzed,in order to provide guidance and reference for the steel box girder hoisting construction in complicated construction environment,such as cross construction phenomenon,large urban road traffic flow.
