浙赣铁路大圆里特大桥曲线预应力混凝土连续梁设计

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

浙赣铁路大圆里特大桥位于半径2 800 m的圆曲线上,跨越杭金衢高速公路,根据地形条件,主桥采用了(52+112+64)m不对称曲线预应力混凝土连续梁。介绍大跨度不对称曲线预应力混凝土连续梁桥的设计和成桥后的静、动载试验。

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 topography 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.
