Background: This cable-stayed bridge is a transportation artery connecting two important areas in a certain city, with a huge daily traffic flow and a long construction time. The structural condition needs to be closely monitored.< br/>
Monitoring technology: using fiber Bragg grating sensors, strain gauges, displacement sensors, etc. Fiber Bragg grating sensors are used to monitor stress changes in bridge structures, strain gauges are attached to key parts to measure strain, and displacement sensors monitor deflection and displacement of bridges.
Monitoring content: Real time monitoring of parameters such as stress-strain, tension, deflection, and vibration of bridges.. By analyzing these data, determine the health status of the bridge structure.
Achievement: A local stress anomaly caused by the passage of an overweight vehicle was detected in a timely manner, and relevant departments were notified through the warning system to avoid potential safety hazards.. The accumulation of long-term monitoring data provides a scientific basis for the maintenance and reinforcement of bridges.
