Design and static analysis of the Taizhou Yangtze River Bridge, China

Abstract

The Taizhou Yangtze River Bridge in China is a triple-pylon suspension bridge with double main spans of 1080 m; it is the world's first triple-pylon suspension bridge with double main spans larger than 1000 m. This paper presents the general design feature and innovation, global static analysis and construction of the main channel bridge, including the introduction of the general behaviour of a triple-pylon suspension bridge, the foundation and block of anchorages, foundation and shaft of pylons, steel box girder, main cable, cable band, main cable saddle, splay saddle, as well as the friction factor experiment between the main cable and main saddle.
