摘　　要：为了解决“32 1”装配式公路钢桥承载力不足、桥面较窄、疲劳寿命较低等问题而设计的 ZB- 2 0 0型装配式公路钢桥是一种由单销连接桁架结构主梁的下承式桥梁 ,其主要性能已达到当前国际同类产品的先进水平 ,对提高我国国防交通保障能力。Type-ZB-200 prefabricated highway steel bridge is a through arch type with the truss main girder pin-connected, which is designed to solve the problems of the insufficient bearing capacity, the narrow surface and the low fatigue life of the existing '321'steel bridges.It is internationally advanced in performance and it may play an important role in improving the national defense traffic guarantee and perfecting the traffic system in wartime.
