摘　　要：大件运输通常指采用特殊车辆运输不可解体或需分解运输的货物,车辆的尺寸、宽度、高度及质量均超出常规车辆。但桥梁基本按照标准荷载设计,需评估大件运输通行桥梁的通行能力。国内相关方法研究较多,如实际荷载计算法、等代荷载法、活载效应比较法和荷载试验法等。某变压器大件运输车辆需要通过某干线公路的一座桥梁,文章通过活载效应比较法结合现场荷载试验对该桥大件运输通行能力进行评估,旨在为类似桥梁大件运输安全通行提供参考。Large cargo transportation usually refers to the use of special vehicles to transport goods that can not be disintegrated or need to be decomposed.The size,width,height and quality of vehicles exceed those of conventional vehicles.However,the bridge is basically designed according to the standard load,and the bridge traffic capacity for the large-cargo transportation needs to be evaluated.There is a lot of research on relevant methods in China,such as actual load calculation method,equivalent load method,live load effect comparison method and load test method.A large cargo transportation vehicle of a transformer needs to pass a bridge on a trunk highway.This paper evaluates the large cargo transportation traffic capacity of the bridge through the live load effect comparison method combined with the field load test,aiming to provide reference for the safe passage of large cargo transportation on similar bridges.
