斜拉索基频识别技术

On identification technique of fundamental frequency of stayed cable

重点介绍了频率法测试索力的振动原理,长、短斜拉索基频的识别方法,对比崖门大桥三次长期监控索力测试结果,并分析索力变化的原因,为斜拉桥设计提供了依据。

The paper mainly introduces the vibration principle for the frequency method to test the cable force and the identification methods for the fundamental frequency of the long and short stayed cable,compared the test results of the three long-term supervision of the cable force at Yamen Bridge,and analyzes the reasons for the changes at the cable force,so as to provide the reference for the design of the cable-stayed bridge.
