摘要

Wufengshan Yangtze River Bridge is a steel truss suspension bridge with a main span of 1,092 m. It is the first suspension bridge in China for high-speed railway and expressway. The bridge was designed as a 4-track high-speed railway and an 8-lane expressway, with a main cable span arrangement of (350 + 1092+350) m and a stiffening beam span of (84 + 84+1092 + 84+84) m. The stiffening beam adopts a large section integral welded structure, with a Warren truss style facade and a straight main truss form with auxiliary trusses in the cross-section. The railway and expressway are arranged at lower and upper layers, respectively, both of which are fully welded structures of plate truss combined with orthotropic overall bridge decks. The operation test data shows that the static and dynamic performance of the bridge structure meets the safety and comfort requirements of high-speed train operation. The high-speed railway has set multiple world records for suspension bridges with a measured speed of 275 km/h.
