摘　　要：为确定杭州湾跨海大桥车辆荷载分布特性,使用动态称重系统采集了为期一年的监测数据。依据车轴数对所有车辆进行了分类,研究了杭州湾跨海大桥交通流分布特性、车重极值以及车辆疲劳荷载谱,以期为大桥交通运营、养护与加固设计以及疲劳车辆荷载模型研究提供参考。研究表明,杭州湾跨海大桥整体交通运营状况良好,外推车重极值远高于D60规范中的车辆荷载取值。In order to determine the distribution characteristics of vehicle load in Hangzhou Bay Sea-Crossing Bridge,the weigh-in-motion(WIM)system was used to collect the monitoring data for one year.All vehicles were classified according to the number of axles.Traffic characteristics,extreme truck weight and fatigue load spectrum in Hangzhou Bay Sea-Crossing Bridge were analyzed,which could be taken as reference for traffic management,maintenance and reinforcement design,and fatigue-loaded vehicle model research.The research shows that the traffic operation of Hangzhou Bay Sea-Crossing Bridge is in good condition,the extrapolated extreme truck weight is much higher than the value of vehicle load in D60 specification.
