摘　　要：桥面铺装是桥梁行车体系的重要组成部分 ,它对桥梁耐久性 ,保证行车安全、舒适度以及经济效益和社会效益有着极其重要的作用 ,是大跨径钢桥建设中的一项关键技术 ,该项技术也是大跨径钢桥建设的世界性难题。本文采用通用有限元分析软件SAP93程序对润扬大桥钢桥面铺装层进行力学分析 ,研究了沥青混凝土铺装层的应力、应变和变形分布的变化规律。根据分析结果 ,提出润扬大桥及类似大桥钢桥面铺装的设计指标。Pavement on bridge is an important part of vehicle system,it plays an important role not only in bridge durability,vehicle safety and comfortable level but also in economic benefit and social benefit And it is a key point in constructing long?span bridge this kind of technology is also a worldly question In the paper,the mechanical properties of steel bridge pavement of Ruenyang Bridge is analyzed by using Finite. Element Method(FEM). The distribution of the stress,strain and deformation in the asphalt concrete surfacing is studied Based on the analysis result,the desing indexes of Ruenyang Bridge and the interrelated bridge are proposed
