摘要
桥面铺装是桥梁行车系的主要组成部分 ,其直接影响行车的安全、舒适性和桥梁的耐久性 ,是大跨径钢桥建设的一项关键技术。将正交异性钢板和铺装层作为受力整体 ,建立有限元分析模型 ,分析了铺装层应力的分布和变化规律 。
Pavement on bridge is an important part of vehicle system, if plays an important role 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 if also a worldwide problem. The finite element model is established in this paper uniting the orthotropic steel deck and pavement, and the avriation of tensile stress in the surface for a typical steel deck surface system is analyzed. The researches provide the theoretic basis for the design and study of steel deck bridge pavement.
