摘    要:本文介绍了一种实时测量桥梁挠度的方法。大量的实验分析数据表明:采用QY型倾角仪测量得到的桥梁挠度时程曲线有很高的精度,从而为桥梁的安全性评价和工程验收提供了可靠的依据。该方法真正实现了桥梁挠度的动态测量,避免了传统静态测量方法必须采取的封桥措施,提高了检测效率,工程应用前景广阔。

关 键 词:桥梁挠度  实时测量  QY型倾角仪  安全性评价  静态测量

Abstract:A real time bridge deflection measurement method is presented in this paper. Plenty of experiments show that the accuracy of deflection time history obtained by QY inclinometer is high, which provides a dependable basis for bridge safety evaluation and project acceptance. The method avoids closing of the bridge measured, which is inevitable for traditional static deflection testing method. increases the measurement efficiency and has potential engineering application value.
Keywords:bridge deflection  real time measurement  QY inclinometer
