摘要
斜拉悬索协作体系钢桥从以1883年布鲁克林桥为代表的罗勃林体系桥首次正式诞生,到2016年第三博斯普鲁斯海峡大桥建成通车,不断接受质疑和挑战,历经133年,终于向世界证明了其体系的可行性。建立了主跨度为1 092 m的公铁两用斜拉悬索协作体系桥有限元模型,探讨公铁两用斜拉悬索协作体系钢桥的结构受力特点与变形分析,可为该类桥梁的设计施工提供初步的技术支撑。
Represented by Brooklyn Bridge in 1883,Roebling System Bridge was first officially born.Until the Third Bosporus Channel Bridge was completed and opened to traffic in 2016,the railway-railed cable-stayed suspension system bridge is being continuously challenged.After 133 years,it finally proved the feasibility of the system to the world.The finite element model of the main-span 1 092 m rail-road cable-stayed suspension bridge was established,and the structural stress characteristics and deformation analysis of the bridge were discussed.The research results could provide the preliminary technical supports for the design and construction of such bridges.
