“32 1”装配式公路钢桥 (简称“32 1”钢桥 )是在原英制贝雷桁架桥的基础上 ,结合我国的实际情况研制而成的一种快速组装式桥梁。在军事运输、抢险救灾等应急交通保障中 ,发挥了突出的作用。2 0 5国道上的二堡便桥在使用过程中桥面板发生了断裂 ,本文就这种桥面板在设计、生产和使用中应注意的几个问题进行探讨。
The “32 1” prefabricated highway steel bridge (hereinafter referred to as “32 1” steel bridge) is a rapid assembly type bridge developed on the basis of the original British Berea truss bridge and combined with the actual situation in our country. In the military transport, emergency relief and other emergency traffic support, has played a prominent role. In the process of using the bridge on the National Highway 20, the bridge was fractured. In this paper, several problems that should be paid attention to in the design, production and use of the bridge are discussed.
