Pursuit for Industrialized Construction of Nanjing Jiangxinzhou Yangtze River Bridge
Nanjing Jiangxinzhou Yangtze River Bridge is located in Nanjing, China. Its main bridge across the river is a central double-cable plane three-tower cable-stayed bridge. It is the world’s first all-steel-concrete composite cable-stayed bridge with a span layout of 80 + 218 + 600 + 600 + 218 + 80 = 1796 m, pioneered the steel shell-concrete composite structure tower, developed coarse aggregate reactive powder concrete(CA-RPC), and applied it to the main girder of the bridge, forming a lightweight high-performance steel-coarse aggregate reactive powder concrete composite beam. Steel stranded stay cables are also applied to the bridge. The main span of the bridge across the embankment is 78 m prestressed continuous box girder with prestressed corrugated steel webs, and the segmental prefabrication construction technology is adopted for the first time; the south and north approach bridges adopt segmental prefabrication and prestressed concrete box girder. Nanjing Jiangxinzhou Yangtze River Bridge takes industrial construction as the main principle of the structural design consideration and has achieved numerous original technologies in new materials, new structures, and new technologies. This paper will systematically and comprehensively introduce the design standards of the bridge, the overall design of the main bridge, and the development of key components. The design overview of the bridge across the embankment is also attached for further reference.
