| Abstract: |
The main bridge of Wanzhou Yangtze River Railway Bridge is a (168+360+168)m tied arch bridge with continuous steel truss, adopting self-balanced structural system; that is the push force tranfered from arch rib will be balanced by pull force of tied bar, no exterior push force exists. The suspenders adopt “H” shaped steel members, and anti-vibration holes setting of suspenders can prevent wind vibration. The anti-corrosion coating system for steel structure adopts fluorin-carbon dope as the finishing coat. The brdige structural type and anti-corrosion coating system are first adopted in China.The side span was installed by semi-cantilever method supported on temporary pier, while the mid span adopted balanced-cantilever method using sling tower frame, the bridge was closed at midspan. |
