摘　　要：采用ABAQUS方法建立了三维足尺寸钢筋混凝土T型梁桥以及沥青混凝土铺装层实体模型,分析不同荷载工况下铺装层内部以及层间胶结界面的纵、横向切应力变化规律,确定了最不利荷载的位置为横桥向工况二、纵桥向位于L/8的荷位,结果可作为桥面铺装体系力学行为的基础。The solid models of three-dimensional reinforced concrete T-beam bridge and asphalt concrete pavement have been established by using ABAQUS. The variations of longitudinal and transverse shear stress of interior and cementation interface with different load cases were analyzed in this paper. The results showed that the most unfavorable load location was load case 2 at the location of L/8 length, which can be regarded as the basis of mechanical behavior of deck pavement system.
