摘　　要：为给混凝土桥梁桥面沥青铺装层结构设计提供力学依据,提出一种考虑车辆动载与温度变化耦合作用的桥面铺装结构力学响应计算与分析方法(简称DT修正系数法)。通过工程实例,综合对比分析了DT修正系数法与其他计算方法所得力学指标响应值的差异性。结果表明,DT修正系数法得到的各指标响应值比较精准地反映了桥面沥青铺装层的实际工况,推荐采用。In order to provide mechanical basis for the structural design of asphalt pavement of concrete bridge,a calculation and analysis method of mechanical response of pavement structure considering the coupling effect of vehicle dynamic load and temperature change(DT correction coefficient method)is proposed.Through actual engineering,the difference of mechanical index response obtained by DT correction coefficient method and other calculation methods is comprehensively compared and analyzed.The results show that the response values of each index obtained by DT correction coefficient method exactly reflect the actual working conditions of the asphalt pavements.
