The suspender cables in tie bar arch bridge are short, so it is rather difficult to calculate the short cable tension.
系杆拱桥中吊杆索长均较短，对于短索索力的计算存在相当的难度。
In the ambient vibration test, the dynamic characteristics of the bridge and the tension force of the cables under constant load were measured.
进行现场环境振动试验，测量了该桥的竖向、扭转动力特性，以及吊索恒载下的索力。
