摘要
自锚式空间索面悬索桥的体系转换施工方法总体分为两大类,一类为直接张拉吊索进行体系转换施工,另一类为通过临时吊索将主缆初步分开进行体系转换施工。通过在自锚式空间索面悬索桥上应用可转动索夹以及球铰底座,衍生出第3类施工方法:利用可转动索夹以及球铰底座的相互转动,调整主缆的空间线形变化直接进行吊索张拉,此类施工方法较第1类适用范围更大,较第2类施工方法简便、快捷。
The conversion construction method of spatial cable plane self-anchored suspension bridge system is generally divided into two categories： a class of direct tensioned sling system conversion construction,the other is using temporary slings as the main cable initially to separate system conversion construction. Through the spatial cable plane self-anchored suspension bridge using rotating cord clip and ball hinge base,the third construction methods is derived： the mutual rotation of rotating cord clip and ball hinge base,adjust changing in the spatial alignment of main cable directly sling a pull,this kind of construction method has a wider application scope than the first class,and more simple and faster than the second class of construction method.
