多瑙新城多瑙河大桥是一座最近修建的钢箱提篮系杆拱桥,位于匈牙利首都布达佩斯以南约70 km的多瑙新城,跨越欧洲第二大河流多瑙河。该桥全长1 676.8 m,主跨307.8 m,东、西侧引桥分别长302 m、1 067m,主跨是世界上同类桥梁中跨径最大的。主要介绍该桥的设计及初步分析研究,包括主、引桥设计概况,以及主桥结构细节的强度、稳定性及疲劳验算的多层次有限元分析,桥梁振动分析、三维空气动力气流计算及抗震分析等。
Danube Metro Danube Bridge is a recently constructed steel-framed basket tricycle arch bridge located in the new town of Danube about 70 km south of Budapest, Hungary, across Europe’s second largest river, the Danube. The bridge is 1,676.8 m in length with a main span of 307.8 m. The approach yards on the east and west sides are 302 m and 1,067 m, respectively. The main span is the largest span of similar bridges in the world. This paper mainly introduces the design and preliminary analysis of the bridge, including the design of main and lead bridges, the multi-level finite element analysis of strength, stability and fatigue checking of bridge structure details, bridge vibration analysis, three-dimensional aerodynamic flow calculation and seismic analysis Wait.
