摘　　要：常泰长江大桥天星洲专用航道桥为钢桁梁拱桥,起始节间架设采用桥位现场散件拼装施工,施工难度大,加之本项目自身特有的地形复杂、安装高差大、单根杆件重量大等不利因素,加剧了起始节间施工难度。重点介绍了天星洲专用航道桥0号墩起始节间施工方案的形成过程,为后续类似工程提供借鉴。The Tianxingzhou Special Channel Bridge of Changtai Yangtze River Bridge is a steel truss girder arch bridge.The construction of the initial section is carried out by assembling the parts at the bridge site,which is very difficult.In addition,the project's unique terrain is complex,the installation height difference is large,the weight of a single member is large,and other adverse factors aggravate the construction difficulty of the initial section.This paper focuses on the formation process of the construction scheme for the initial section of Pier 0 of Tianxingzhou Special Channel Bridge,which provides a reference for similar projects.

关 键 词：常泰长江大桥 天星洲专用航道桥 钢桁梁拱桥 钢梁架设 起始节间
