长沙火星大道浏阳河大桥设计研究

Design and Structure Analysis of the Liuyang River Bridge in Changsha City

长沙火星大道浏阳河大桥是跨越浏阳河的特大桥梁主跨为138 m,宽39.8 m的中承式钢箱拱桥。主桥为“类双层”结构,横梁底部悬挑人行道挑梁,形成人车分离的双层结构。浏阳河大桥在设计阶段进行了静力分析研究、稳定分析及关键部位的细部分析,通过这些分析确保浏阳河大桥设计的安全、合理。浏阳河大桥的成功建设为类似桥梁的设计、建设提供理论参考。

Liuyang River Bridge is a steel box half-through arch bridge with the 138 m spans and 39.8 m widths in Changsha. The bridge was the double layer, pavement cantilever beam from the Tran beam. During the stage of design, static analysis dynamic analysis and detail analysis were carried out, which made the structure safe and rational. These conclusions could be used for reference in the construction process of this kind of bridges.
