摘要
山东省济南市凤凰黄河大桥主桥采用三塔双索面自锚式悬索桥,跨径布置为70 m+168 m+428 m+428 m+168 m+70 m.加劲梁为采用新型正交异性组合桥面板的组合梁结构,混凝土板与钢桥面板之间采用焊钉连接件连接为整体来共同受力,具有较高的承载力和较好的耐久性能.文章结合三塔自锚式悬索桥主梁的受力特点,详细介绍了凤凰黄河大桥主桥的主梁结构构造设计,并通过整体和局部计算对其关键受力性能进行了分析.结果表明,采用组合板组合梁结构可很好地保证结构的安全,具有较好的经济性.
Abstract
The main bridge of Fenghuang Yellow River Bridge in Jinan City of Shandong Province is a self-anchored suspension bridge with three towers and double cable planes.The span arrangement is 70+168+428+428+168+70 m.A new type composite structure with orthotropic composite bridge deck is used as the stiffening girder,the concrete slab and the steel bridge deck are connected by stud connectors to bear the force together,which makes the stiffening girder high bearing capacity and good durability.Based on the mechanical characteristics of the main girder of the three-tower self-anchored suspension bridge,the main girder design details are introduced for the main bridge of the Fenghuang Yellow River Bridge,and the key mechanical properties are analyzed through overall and local calculations.The results show that this new composite structure with orthotropic composite bridge deck can ensure the safety of the bridge and has good economy.
