Abstract
The fourth Qiantangjiang River Bridge is a double-deck bowstring arch bridge of concrete-filled steel tubes with main spans each 190 m.The type of the bridge is novel and technically complicated with a number of innovations in aspect of structural types,bridgescape design,theoretic analysis,experimental study and construction technology.In this paper,several key techniques of the Bridge are described.
