自锚式悬索桥施工控制

Construction Control of Self-Anchored Suspension Bridges

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。

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 example the authors introduced the method of analysis of cable shape at cable-finished stage and construction control of straining of hangers and some useful conclusions were drawn. The result would give some guidance for the similar engineering.
