该文利用有限元数值模拟方法对简支箱梁桥沥青混凝土桥面铺装进行分析，计算不同弹性模量及铺装层厚度时铺装层间应力变化规律，认识沥青混凝土桥面铺装层受力基本特性，得出铺装层厚度的合理范围，指导沥青混凝土桥面铺装层的设计和施工。%With finite element stress analysis numerical simulation, bituminous concrete pavement of bridge deck with simply supported box-girder is analyzed and stress variation rule of pavement layer with different elasticity modulus and different thickness is obtained. Basic mechanical characteris-tics of bituminous concrete pavement are analyzed and reasonable thickness range is got. It can offer some references for similar projects.
