摘　　要：以某斜拉桥健康监测系统为基础,介绍了动态交通荷载监测系统的应用。通过动态交通荷载监测系统,得到特定情况下行驶车辆的出现及车辆的重量、车速、轴距、车辆类型以及有关车辆的其他参数。同时通过实际车辆荷载作用下桥梁结构响应与计算值的比对,得出桥梁结构实际承载能力情况,为今后该地区公路桥梁的运营提供真实的荷载依据,同时也为桥梁结构整体性能评价提供参考。Based on the structural health monitoring system of a cable-stayed bridge,the application of dynamic traffic load monitoring system is introduced.Through dynamic traffic load monitoring system,the weight,speed,wheelbase,type and other parameters of the driving vehicle under certain circumstances are obtained.And through the comparison between actually structural response of bridge and calculated values,the actual carrying capacity of the bridge structure is obtained.It proposed the practical vehicle operation load in this region,and provided the scientific basis for integrity performance evaluation of cable-stayed bridge structure.
