摘　　要：以济青高速改扩建工程为例,利用动态称重系统(Weight-in-Motion,WIM)实测数据分析了2019年至2020年的济青高速公路的交通轴载分布特征,获得了不同轴型车辆的轴载谱变化规律;通过对全年交通量的分析,得到了车道拓宽后的高速公路年平均日交通量调节系数及车辆横向分布系数的变化规律。研究结果表明:采用轴载谱的方法可以更加全面、精确地分析交通荷载对路面结构产生的破坏机理,可以为类似区域条件下道路设计分析提供基本的交通输入参数。Taking the reconstruction and expansion project of Jinan-Qingdaoexpressway as an example,the traffic axle load distribution characteristics of Jinan-Qingdao expressway from 2019 to 2020 are analyzed by using the measured data of weight in motion(WIM),and the variation rules of axle load spectrum of vehicles with different axle types are obtained;the variation laws of annual average daily traffic volume adjustment coefficient and vehicle transverse distribution coefficient of expressway after lane widening are obtained through the analysis of annual traffic volume.The research results show that:the axle load spectrum method can more comprehensively and accurately analyze the failure mechanism of traffic load on pavement structure,and provide basic traffic input parameters for road design and analysis under similar regional conditions.
