摘　　要：基于图像摄影技术对平潭海峡大桥挠度进行长期监测,分析各类荷载作用下平潭海峡大桥挠度变化规律,确定车载对大桥的挠度影响程度.重点研究了不同车型活荷载与桥梁挠度之间的关系,分析结果表明车辆荷载与挠度具有良好的正相关性.该数据分析为平潭海峡大桥的安全鉴定和寿命评估提供了良好的技术支撑,为桥梁检测技术提供借鉴.Based on the image shooting technique,the deflection of the Pingtan Strait Bridge is monitored for a long time.The deflection law of the Pingtan Strait Bridge under different loads is analyzed,and the influence degree of the vehicle on the deflection of the bridge is determined.This paper focuses on the relationship between the live load of different types of vehicles and the deflection of the bridge.The analysis results show that the vehicle load and deflection have a good correlation.The data analysis provides a good technical support for the safety assessment and life assessment of the Pingtan Strait Bridge,and provides reference for bridge inspection technology.
