摘要
文章利用毫米波雷达技术对某系杆拱桥的动挠度、基频进行运营期智慧化在线监测,并与现有其他非在线测量结果进行比对分析,验证毫米波雷达在桥梁监测中应用的可靠性。通过对比毫米波雷达与光电挠度仪的动挠度测试结果,与加速度传感器的基频测试结果,表明毫米波雷达在桥梁动挠度、基频监测的测试结果是可靠的,研究成果可为类似工程提供参考。
This article uses millimeter wave radar technology to intelligently online monitor the dynamic deflection and fundamental frequency of a tied arch bridge during operation,and compares and analyzes it with other existing non online measurement results to verify the reliability of millimeter wave radar application in bridge monitoring.By comparing the dynamic deflection test results of millimeter wave radar and photoelectric deflection instrument with the fundamental frequency test results of acceleration sensor,it is shown that the test results of millimeter wave radar in bridge dynamic deflection and fundamental frequency monitoring are reliable,and the research results can provide reference for similar projects.
