Design of Prestressed Concrete Curved Continuous Girder of Dayuanli Bridge on Zhejiang-Jiangxi Railway

Located on the round curve with a radius(2 800 m,) the Dayuanli Bridge on Zhe-jiang-Jiangxi Railway spans the Hangzhou-Jinhua-Quzhou Expressway.In the light of the topo-graphy conditions at the Bridge site,the main bridge of the Bridge is designed as a asymmetric prestressed concrete curved continuous girder structure with span arrangement(52+112+64) m.In this paper,the design of the long span asymmetric prestressed concrete curved continuous girder bridge,and static and dynamic load tests for the completed bridge are described.
