The main works are as follows: 1 The developingt history of the traffic load on bridges is represented. Typical bridge codes in some countries are discussed and these traffic load models are comparative analyzed. Analysis shows that the influence of layout axle for the total traffic load effect on bridge gradually becomes smaller with the increase of bridge span. So most national norms use the distributed load as the equipollent load of traffic load.

主要内容包括下面几个方面： 1阐述了桥梁汽车荷载发展的简史，讨论了部分国家典型的桥梁汽车荷载设计规范，并对这些荷载模型进行了对比分析，分析表明随着桥跨的增大，车轴布置对桥梁整体荷载效应的影响逐渐变小，因而大部分国家的规范都把均布荷载作为车辆的等代荷载。
