Abstract
In this study, a new approach for estimation of river flow state such as water level, flow velocity and flow as well as stability of bridge is proposed using time series analysis of vibration signal measured using accelerometer mounted on the bridge during flood. In detail, a simple vibration model consisting of river flow and bridge pier is prepared, and a discrete model is developed, and then the correlation between mechanical parameters and time series model parameters is discussed. Next, the actually measured vibrations signal during usual time and flood are investigated in time region, and are analyzed using the corresponding discrete time series model. It is therefore revealed that the river flow state and the stability of bridge can be estimated by monitoring the change in AR parameters of the measured time series vibration signal.
