| Abstract: |
This paper introduced the layout span of viaduct in front of new Wuhan railway station, stress characteristics, calculation method, and the special design which is different from the straight girder bridge because of the stress characteristics of small radius and large curvature. It mainly contains the box girder structure, prestressed tendons arrangement, piers eccentric setting, and reasonable selection of supporting pattern. Besides, the layout of the two kinds of reinforcement has been studied. One is used against collapsing of prestressed tendon on the radial direction, and the other is the stirrup bar for resisting against the torque effect. As a result, this research could provide reference for the related bridge design in the future. |
