本文以重庆市渝州路道路拓宽改造工程2号人行天桥为例,对简支下承式拱形钢桁架结构在大跨度天桥工程中的实际运用进行了介绍,并重点分析了该天桥的结构选型、总体布置、桁架杆件和节点构造,对类似结构的桥梁设计具有一定借鉴意义。

Abstract:

SThis paper takes the No. 2 pedestrian bridge of the road widening and reconstruction project of Yuzhou Road in Chongqing as an example, and introduces the practical application of the simply-supported bottom-through arch steel truss in the long-span pedestrian bridge, and focuses on structure selection, general layout, truss rod and node of the bridge, which has reference significance for the design of similar bridge.
