Application of Health Monitoring System in Bridge Operation
In order to explore the accuracy of the application of health monitoring system in bridge operation,this paper introduces the design and implementation of the health monitoring system of the bridge based on the project of Junken No.1 Bridge(prestressed con-crete cable-stayed bridge of single tower-double cable plane)in Shihezi City.Six regular monitoring of the structure has been com-pleted so far,based on the monitoring data of the sixth time,combined with the comparative analysis of the monitoring results of the first 5 times,it can be seen that the cable force is basically not more than±3% compared with the design value,the coincidence degree is good.And the stress monitoring value of main girder and tower is far less than the control section stress.The elevation monitoring values on both sides of the bridge deck are close to the design values and higher than the design values.The results show that the health moni-toring system has a good application effect in the bridge,which can ensure the accuracy of the early warning of the bridge structure and provide data support for accurately judging the health status of the bridge in operation.
