摘    要:安庆长江大桥为大跨度钢桁梁斜拉桥,桥上铺设无缝线路.大跨度斜拉桥结构复杂,为塔-索-梁空间组合体系,铺设无缝线路后,在荷载作用下,会形成"塔-索-梁-轨"藕合作用体系,其无缝线路力学传递机理较一般桥上无缝线路更为复杂.通过建立大跨度斜拉桥"塔-索-梁-轨"耦合模型,对安庆长江大桥桥上无缝线路纵向力进行计算分析,比选大跨...

关 键 词:大跨度  斜拉桥  无缝线路  设计方案

Abstract:The Anqing-Changjing Bridge is a large-span cable-stayed steel truss bridge,and the continuously welded rails are laid on the bridge.Since,the large-span cable-stayed steel truss bridge has a complex structure,after the continuously welded rails are laid,the load will make the bridge a coupled system of towers,cables,girders,and rails.The mechanism of force transition of the continuously welded rails on such a bridge is more complicated than that on other bridges.By setting a coupled model of towers,cables,...
Keywords:large-span cable-stayed bridge  continuously welded rail  designing scheme  expansion rail joint
