Abstract
The Hejiang Yangtze River Highway Bridge is located in Hejiang County, Luzhou City, Sichuan Province, China, whose main bridge will be the largest span of fly-bird CFST arch bridge in the world, with the span arrangement of 80.5 m + 507 m + 80.5 m, which is currently under construction. The arch rib for middle span is a half-through concrete-filled steel tube truss rid arch, and the arch ribs for side span are half-arches of concrete cantilever with concrete-filled steel tube skeleton inside. This paper mainly introduces the structures and design features of the main arch rib and side arch ribs of the bridge, its construction method, especially, the vacuum assisted pumping-up pouring method is also introduced. It is hoped to provide reference for the design of other such type arch bridges.
