摘要
阐述了下承式小半径曲线景观钢桁架桥的设计要点,重点介绍了曲线桁架的结构布置、桁架节间"以直代曲"的处理方法、悬臂式观景台的设计以及桥面铺装方案等,并进行了详细的结构强度及刚度验算,保证了该桥技术上的先进性和经济上的合理性。
This paper introduces the design points of through small radius curve steel truss bridge.It mainly includes the structural arrangement of curved truss,the processing method of " straight lines instead of curves" between truss nodes,the design of cantilever viewing platform and the paving scheme of bridge deck.The structural strength and stiffness are checked in detail.The technical advancement and economic rationality of the bridge are guaranteed.
