摘要
为满足桥下通航及防洪要求,东宝河波形钢腹板PC组合箱梁特大桥主跨采用156m,双向桥面各宽16.25m,每幅按单箱单室设置,中墩箱梁根部梁高8.3m,按1.6次抛物线过渡到跨中梁高3.5m。文中介绍了该桥的主梁结构、预应力体系、波形钢腹板、连接件、施工流程等内容,为以后同类桥梁的设计和施工提供参考。
For the requirements of the bridge navigation and flood control,the main span of Dongbaohe corrugated steel webs PC composite box girder bridge adopts 156m,the bridges around two furnished single deck width 16.25m,each piece by single cell box setting,the height of box girder beam at the pier roots is 8.3m,by 1.6 times parabolic transition to midspan height 3.5m. This paper introduces the main beam structure,prestressed system,corrugated steel webs,connections,construction process and other content. Based on that,the article provides a reference for future design and construction of similar bridges.
