| Abstract: | Wushan Yangtze River Highway Bridge is a half-through concrete-filled steel pipe arch bridge with a main clearance span of 460 m. The erection of main arch ribs adopt cable-stayed buckled method of non-support cable hoisting system, which were closed successfully in this April. The example perfects further for the non-support cable hoisting system in our country. Among them, the key techniques in hoisting construction are further broken through, it may be used for technique reference for arch bridge construction. |
