摘　　要：随着经济的高速发展,大型重型运输车辆增多,公路超载现象日益严重。为了解安庆长江公路大桥车辆运行的实际情况,分析车辆荷载对结构的影响,文章通过动态称重系统对车辆荷载等参数进行统计,结合健康监测系统数据,对桥梁跨中挠度变化的主要原因进行分析,以期为桥梁的养护管理和健康运营提供参考。As economy develops, overloading trucks become more serious in most highways. In order to investigate the vehicle loading and their impact on bridge structural performance of Anqing Yangtze river bridge, statistical analysis is conducted for parameters such as vehicle loading by means of WIM（weigh in motion）, and SHM（structural health monitoring） data are also utilized for cause analysis of bridge mid-span deflection, which could be taken as reference for bridge maintenance and operation.
