| 摘 要： | 吊杆拱桥的吊杆更换过程中需要对一系列的吊杆索力进行监测,由于吊杆长度较短,无法直接应用振动频率法监测吊杆索力.为此,分析了吊杆更换施工过程中索力监测的内容和方法,并提出采用振动频率法监测吊杆索力的新方法,工程实例应用证明这种方法简单、有效且实用.

| Abstract: | Suspender cable force monitoring should be carried on in the entire replacing process of arch bridge suspender. Vibration method is not applicable to the short suspender. This paper proposes the method and content for cable force monitoring during the suspender replacing, and puts forward a new method of vibration for monitoring. Engineering example proves that the method is simple, effective and practical. |
