Research on Rapid Evaluation Method of Cable-stayed Bridge Based on Health Monitoring System
The load test is the most important means to evaluate the bearing capacity of the bridge,but the traditional load test has a long loading time,high loading cost,and needs to close the traffic.Based on the comparison between the measured and actual measured values of the health monitoring system,it is found that the measured values are in good agreement with the theoretical values when the single-lane vehicles are loaded,which can replace the conventional static load test to a certain extent.When multiple lanes are loaded at the same time,the deformation in the middle of the span is better at the place.The results show that the rapid load test evaluation method based on the health monitoring system is fast,has little impact on traffic,and has high test efficiency,which can realize the rapid evaluation of the bridge at any time,and provide a basis and reference for regular maintenance and daily maintenance management.
