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.
