600t级运输车辆需通过贝雷式钢便桥。钢便桥采用贝雷式321型桁架单元,总长度228m,共19跨每跨12m,上承式结构。介绍了架桥点选取和便桥的结构布置及设计注意事项,提出了钢便桥使用维护措施。实际应用表明,钢便桥安全可靠,保障了大件运输车辆的通行。
The portable steel, bridge for the vehicle of transporting 600 t large parts is made of Bailey truss units of type 321. Its overall length is 228 m （19 ×12 m）, deck-type structure. Both the selection of the bridge site and design load, and the structural layout of such kind of portable steel bridge, and the problems needing attention during design process were described. The practical results during operational periods show that the bridge is safe and good for the vehicle to transporting 600 t large parts.
