摘要
基于城市轨道交通接触网系统中双承力索、双接触线张力比较大这一特殊情况 ,结合上海轨道交通 3号线一期工程的具体实践 ,介绍了张力等效负载法的应用方法及原理。
Since the strain of erecting double contact wire of overhead contact system in urban rail transition is quite great, the author integrates the experience of construction of Shanghai Pear1 Line 1 in the first phase and holds that the application of equivalent load about strain to double wires in contact networks is safer and more reliable in the process of installement.
