Construction Technologies of a large span Railway Suspension Bridge- Wufengshan Bridge

This paper is to introduce construction technologies of a thousand-meter scal high-speed railway suspension bridge in China, Wufengshan Bridge. There are basic principles applied throughout the bridge construction process: 1) To pay attention to innovations in bridge design method and basic theory by emphasizing both life cycle optimization design and durability design; 2) To advance key bridge construction technology; 3) To grasp the state deterioration mechanism and evolution law of the bridge operation and maintenance process in advance; 4) To build a whole life-cycle management framework system. This paper involves the design method, calculation theory, and the corresponding technical standards of high-speed railway suspension bridges in China.
