摘要本文系统地阐述了自锚式悬索桥施工控制的方法。空缆线形计算是自锚式悬索桥施工控制的
关键环节,通过张拉吊杆可以使自锚式悬索桥达到理想的线形。本文结合工程实例详细介绍了自锚式
悬索桥空缆线形计算的方法以及吊杆张拉施工过程的控制,并得出了一些有意义的结论,对其他类似工
程具有一定的指导作用。

Abstract This paper introduced the construction control method of self anchored suspension bridges. Analysis
of cable shape at cable finished stage is the key of construction control of self anchored suspension bridge. And
then we could gain the perfect shape of self anchored suspension bridge by straining. Through an examp le the
authors introduced the method of analysis of cable shape at cable finished stage and construction control of
straining of hangers and some useful conclusionswere drawn. The resultwould give some guidance for the sim i
lar engineering.
