摘要
介绍了微变形监测雷达的监测原理、基本性能指标,对比分析了微变形监测雷达和加速度计、全站仪的监测结果并采用微变形监测雷达对宝成铁路下行线清江2#桥和上行线清江7#桥进行健康监测。比对试验和应用成果表明,微变形监测雷达用于桥梁工程健康监测中的振动频率、振动速度和振动变形的实时跟踪监测是合理可靠的,测量结果精确。
This paper introduces the monitoring principle and basic performance indexes of movement and surveying radar, compares it＇s monitoring results with accelerometer and total station. The movement and surveying radar is also used in of Baocheng railway. The test and application results indiciate the monitoring of Qingjiang 2# bridge and 7# bridge is reasonable and accurate in monitoring of vibration frequency, vibration velocity and vibration deformation for bridge healt monitoring.
