特种重载车辆荷载下的钢便桥设计

Design of Steel Temporary Bridge under Special Overload Vehicle Load

大型设备的运输往往采用特种重载车辆,某工程实例车辆荷载标准达到总重526 t、轴重34 t,采用了新建临时便桥的通行方案。临时便桥上部结构主要采用321型标准钢桁梁,下部结构主要采用钢管桩基础。通过对在特种重载车辆荷载下的钢便桥设计方案的介绍,可为设计人员在类似桥梁设计时作为参考。

The special overload vehicle is often used for the transportation of large-sized equipment In an engineering case,the vehicle load standard is gross weight 526 t and axle load 34 t.The newly built temporary bridge is used in the passing schema The superstructure of temporary bridge is nnainly the type 321 standard steel truss bearn and the substructure is nnainly the steel pipe pile foundation.The article introduces the design scheme of steel temporary bridge under the special overload vehicle load,which can be referred for the design of the similar bridges
