摘　　要：汽车荷载作为桥梁重要的可变荷载之一,其值的大小直接影响桥梁的安全。随着交通运输的快速发展,桥梁实际的营运荷载可能超过设计汽车荷载,在进行既有桥梁评估及加固维修时,汽车荷载的选取应反映桥梁实际的运营状况。该文基于采集的江苏省内某条高速公路350万条动态称重系统实测数据,对影响桥梁汽车荷载效应的参数进行分析,其中包括交通流的特征、车型分布、汽车总质量分布、车间距分布等。并对影响汽车荷载效应的各参数进行分布拟合,对比得到最优的拟合方案。As one of the important variable loads on bridges,the value of automobile load directly affects the safety of the bridge.With the rapid development of transportation,the actual operating load of bridges may exceed the design vehicle load.When evaluating and reinforcing existing bridges,the selection of vehicle load should reflect the actual operating condition of the bridge.This paper is based on the collected 3.5 million Weighing-In-Motion System test data of a certain highway in Jiangsu Province,and analyzes the parameters that affect the bridge vehicle load effect,including the characteristics of traffic flow,vehicle type distribution,total vehicle mass distribution,vehicle spacing distribution,etc.The distribution of various parameters that affect the vehicle load effect is fitted,and the optimal fitting scheme is obtained by comparison.
