随着我国大跨径桥梁的增多，现有的装配式结构已无法满足应急抢修工作的需要，其存在的主要问题是跨越能力有限。文章利用现有321型和 HD200型的产品库存及其多排多层的拼装方式，提出了一种易于架设的组合桁架式装配式公路钢桥，大大提高了该类结构的跨径，并对其组成构件、连接构造、计算理论及受力进行分析，为该类桥型的设计提供了参考。

With the increase of large span bridges in China ,the existing assembled‐type structure has been unable to meet the requirement of the emergency repair w ork ,and the main problem is the finite span .In this paper ,a kind of truss‐type assembled highway steel bridge is presented ,which makes full use of inventory and multi‐slice assembly of the existing assembled type‐321 and type‐HD200 products and improves the span of the bridge greatly .And the structure design of the component , connection ,calculation theory and force analysis are introduced ,w hich can provide a reference for the design of assembled highway steel bridge .
