摘　　要：基于磁弹效应原理,以磁通量传感器为手段,建立斜拉桥索力测试系统。该监测系统是一个适用于桥梁拉索监测的平台,可用于远程实时及长期监测、分析现有桥梁拉索的状况。将监测系统应用于北京市某斜拉桥上进行索力监测,比较监测结果与索力设计值后,发现两者具有较好的一致生,监测值较准确,可满足工程上的精度要求。Inthe paper, the cable force monitoring system based on magnetoelastic effect, by means of electromagnetic sensors, is built and used on one cable-stayed bridge in Beijing, which may achieve online auto monitoring the cable force of cable-stayed bridge. The monitoring system results and the design results of cable force are compared and they have good consistency,so the monitoring system results is accurate and can meet engineering requirements,and the monitoring system may be used in online auto monitoring the cable force of cable-stayed bridge.
