摘要
某跨铁路大桥采用(40+88+252+88+40)m独柱塔中央索宽幅钢箱梁斜拉桥,桥宽44 m,半漂浮体系,转体法施工。通过介绍该桥结构体系、桥塔选型、主梁选型、塔梁临时固定、防撞防抛体系、桥面铺装体系等关键技术及研究成果,为结构设计参数取值、关键构造设计提供指导。研究成果丰富了跨铁路桥梁结构形式,可为同类型桥梁工程提供重要借鉴和参考。
A railway crossing bridge adopts(40+88+252+88+40)m single column pylon central cable wide steel box girder cable-stayed bridge with bridge width of 44 m,semi floating system and swivel construction.Through the introduction of the key technologies and research results of the bridge structure system,tower selection,main beam selection,temporary fixing of pylon and girder,anti-collision and anti throw system,bridge deck pavement system and so on,this paper provides guidance for structural design parameters and key structural design.The research results enrich the structural form of the bridge across the railway,which can provide important reference for the type of similar bridge engineering.
