摘要
拉索是斜拉桥的主要传力结构,索的健康状态将直接决定着桥梁的正常运营。现系统阐述了基于压力传感器的索力监测法、基于振动频率的索力监测法、基于电磁传感器的索力监测法、光纤光栅监测法及声发射监测法等几种主要的拉索健康监测技术的基本原理,并对其适用性进行了讨论,为斜拉桥拉索健康监测提拱了有力依据。
Suspender is the main force transmission structure of cable-stayed bridge,the health status of the suspender will directly determine the normal operation of the bridge.In this paper,the basic principle and applicability of the cable force monitoring method based on pressure sensor,vibration frequency,electromagnetic sensor,fiber brag grating monitoring and acoustic emission monitoring were described.These technologies provided a strong basis for the health monitoring of cable-stayed bridge.
