摘　　要：沥青铺装层作为桥面铺装结构的上覆盖层,直接承受车轮的碾压和冲击,并将荷载分散到下层结构中去。为了研究沥青铺装层对层间粘结性能的影响,利用有限元软件ANSYS建立了混凝土桥梁沥青桥面铺装整桥有限元模型,分析沥青铺装层结构的层间应力变化规律。研究结果表明:采用两层沥青铺装的沥青桥面铺装结构,随着铺装上层、下层厚度的增加可以提升层间抗拉性能,但提升的效率随厚度的增加而降低。The asphalt pavement layer,as the upper covering layer of the bridge deck pavement structure,directly withstands the grinding and impact of the wheels,and disperses the load into the substructure.In order to study the influence of asphalt pavement layer on the interlayer bonding,a finite element model of asphalt bridge deck pavement for concrete bridges was established using the finite element software ANSYS,and the variation law of interlayer stress in the asphalt pavement layer structure was analyzed.The research results indicate that:the asphalt bridge deck pavement structure using two layers of asphalt pavement can improve the interlayer tensile performance as the thickness of the upper and lower layers of the pavement increases,but the efficiency of the improvement decreases with the increase of thickness.
