江阴长江公路大桥钢桥面铺装设计

Pavement Design of Yangtze River Highway Bridge in Jiangyin

钢桥面沥青混凝土铺装是大跨径桥梁建设的关键技术之一,备受世界各国工程界的高度重视。江阴大桥采用了浇注式沥青混凝土桥面铺装,在国内尚无工程实例。文章从材料结构、性能试验、有限元分析等方面介绍江阴大桥钢桥面铺装设计,从荷载调查及应力应变的变化分析了桥面铺装病害成因。

Bitumen concrete pavement, a core technology in big-span bridge, is deemed highly important by engineering circle of every country in the world. Bitumen concrete cast-in-site for Jianying Bridge deck pavement fills the blank of construction record in China. This article tells the material, structure, quality test, finite element analysis of the said bridge, and analyzes the cause of disease of the bridge pavement from the survey on the load and variation of stress-strain.
