摘　　要：分析了车辆超载的原因,从社会和经济双重层面进行了探讨。研究了车辆超载对桥梁结构性能的影响,包括垮塌失效、疲劳破坏和桥面系破损等层次;分析了影响机理和产生后果;提出了保证交通运输及桥梁结构性能的对策和方法,以应对我国的超载问题。The causes of truck overloading are analyzed from two perspectives of social and economic aspects. The impact of truck overloading on bridge performance is investigated, and three aspects of structural safety, fatigue safety, and bridge deck damage are studied to analyzed the influence mechanism and influence. Some countermeasures on bridge performance improvement and transportation economic are proposed, to address the current truck over loading issue.
