Long-span bridges play an important role in the people’s daily life and transportation. It is necessary to establish a reliable health monitoring system to maintain the function and safety of long-span bridges. In long-span bridges, monitoring of the vertical deflection under the actual traffic loads is not only crucial to ensure the overall serviceability and safety of the bridge, but also to predict the abnormal state. Micrometers or displacement meters are widely used to measure bridge deflections directly in evaluation of old field bridges and tests of newly built bridge.
