| Abstract: | 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. |
