摘要
涪陵乌江二桥螺旋匝道桥采用双层环形结构,道路中心线半径45.0 m。内、外幅箱梁全桥范围内结构连续,通过大悬臂挑梁,与桥墩连为一体实现墩梁固结。介绍该匝道桥结构形式和受力特点,并就小半径曲线连续箱梁桥的受力特点进行分析。
The spiral ramp bridge of the Second Fuling Wujiang River Bridge is designed as a double-deck loop structure with a radius of its roadway alignment 45.0 m. The inner and outer separate box girders of the bridge are structurally continuous within the range of the overall bridge and the girders and piers are rigidly fixed together through connection of the wide cantilever deck with the piers. In this paper, the characteristics of the structural form and behavior of the bridge are presented and the structural behavior of the curved continuous box girder bridge with sharp radius is analyzed as well.
