INTRODUCTION OF DESIGN PLAN OF WULONGJIANG BRIDGE ON FUZHOU-QUANZHOU FREEWAY

The design plan of Fuzhou Wulongjiang bridge is introduced in this paper. Its main span is a through prestressed bowstring concrete-filled steel tubular arch based on the demand of investment office and the natural conditions of the bridge site and hydrological geology. It has the advantages of dextrous model, advanced technique, convenient construction and low cost, and it can lower the height of approach bridge and embankment to shorten the length of bridge because of its low construction height. The superstructure of approach bridge is designed by partial prestressed concrete and the substructure of approach bridge is designed by beams supported directly on the piles.
