悬索桥主缆安装曲线的解析解

Analytical solution of installing curve of suspended bridge's main cable

悬索桥主缆安装时受到荷载分布、自身变形、温度变化、鞍座偏移等诸多因素的影响 ,因此 ,应预先给出安装阶段主缆曲线的几何坐标 ,对特大桥施工而言 ,这点尤为重要。给出悬索桥主缆安装曲线参数形成的解析解 ,供设计人员和施工工程师参考。

Many factors, such as road distribution, cable stretch, temperature change and deviation of saddle support, will influence the exact positions of suspended bridge's main cable as installing reinforced girder. Therefore it must present the geometric coordinates of the curve of the main cable before installing. This is very important to great bridge construction. The analytical solution of installing curve of suspended bridge with parametric type are presented for engineer reference.
