The Dashengguan Bridge (Chinese南京 大胜关 长江 大桥, english Nanjing Yangtze River Bridge, Nanjing Yangtze River Bridge ') is a railway bridge over the Yangtze River near Nanjing, China. It is one of the longest steel truss bridges whose superstructure is designed as a continuous beam. The bridge has six tracks, which are used by the high-speed Beijing- Shanghai high-speed line of the Shanghai - Wuhan - Chengdu and Nanjing subway.
The building is located about twenty kilometers above the 1968 Nanjing Yangtze River Bridge opened, or about a mile above the Third Nanjing Yangtze River Bridge, which was completed in 2005. The total length of the bridge is 9273 meters. Construction of the bridge began in 2006, on 28 September 2009, the main carrier was completed in 2010 and the whole bridge; the opening to traffic in January 2011.
The Dashengguan Bridge consists of the 1272 -meter-long main beams in steel truss with the two 336 meter long arch, two 168 -meter-long northern bridge spans from parallelgurtigen steel trusses, as well as a northern 1208 feet long and a southern 6450 meters long subsequent to the steel frame box girder bridges reinforced concrete. The continuous beam with bows has three vertical truss planes that are located between the tracks. The extreme use of the subway tracks are the trusses, lie between the trusses, the high-speed lines, the double track the high-speed Beijing- Shanghai respect to the flow direction of the Yangtze River lies on the valley side. The stiffened bridge deck is suspended to hangers ***** length on the sheets.
The run support was built using the balanced cantilever, where the sheets were worn out during the construction phase with mounted pylons. The patch on the already constructed part of the arches cranes were used both to insert the steel beams of the structure, as well as for unloading and assembling of supplied by ship fully assembled bridge deck parts.
