摘要
武汉天兴洲公铁两用长江大桥主桥为双塔三索面钢桁梁斜拉桥,首次采用了3片主桁、三索面的结构形式。该桥设计中研究确定了铁路多线荷载加载等新技术。介绍该桥钢梁的设计要点、结构设计及主要专题研究项目。
The main bridge of Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge is a steel truss girder cable-stayed bridge with double pylons and three cable planes and on the bridge, the structural type of three main trusses and three cable planes is applied for the first time. In the design, several new techniques, such as that of applying multi-track railway load, have been researched and determined. In this paper, the design highlights, structural design and principal special subject study of the steel truss girder of the bridge are dealt with.
