双层预应力混凝土自锚式悬索桥设计

Design of Double-Deck Prestressed Concrete Self-Anchored Suspension Bridge

对悬索桥的发展史与各个发展阶段受力特点进行了介绍,叙述了自锚式悬索桥的主要特点,对近年来国内设计的自锚式悬索桥作了简要统计,指出主要设计趋势;并以国内某座双层预应力混凝土自锚式悬索桥为例,介绍了其主要部位的设计思路,采用MIDAS CIVIL及ANSYS软件进行结构分析,对本桥设计难点进行了总结。最后,对自锚式悬索桥的发展进行了展望。

In this paper, the history of the development of suspension bridges and the mechanical characteristics of each development stage are introduced, the main characteristics of self-anchored suspension bridges are described, the domestic self-anchored suspension bridges designed in recent years are briefly counted, and the main design trends are pointed out. Taking a domestic double-deck prestressed concrete self-anchored suspension bridge as an example, the design ideas of its main parts are introduced, MIDAS CIVIL and ANSYS software are used to carry out structural analysis, and the paper summaries the difficulties in the design of the bridge. Finally, the development of self-anchored suspension bridges is prospected.
