| 摘 要： | 悬索桥加桥头拉索一般用于悬索桥多于三跨或用于三跨悬索桥其边跨的悬索抛物线弓形高f比较大时。桥头索的作用是减小桥头的水平位移,对于桥梁整体稳定有重要作用。首先介绍强力拉索的位移计算方法,然后结合文献1]导出悬索桥加桥头拉索的精确计算方法并应用于实际工程。

| Abstract: | The cables of head tower are generally used for more than three-span suspension bridge or the parabolic arch f of the side span is higher. The role of high strength cable of head of tower is to reduce the horizontal displacement of the bridge head,which is important to overall stability of the bridge. This paper introduces the displacement calculating method of the powerful cable and then educes the precise calculating method of suspension bridge with cables of head by combining with the reference1],which is applied to a suspension bridge. |
