Anomaly Diagnosis of Bridge Piers Using an Acceleration Pickup

Abstract

In a case of flood, earth and sand at the bottom of bridge piers are sometimes scoured and thus yields unstableness of the bridge piers. Therefore, constant monitoring of bridge piers is of great importance in keeping the safety operation of trains. The paper thus proposes a simplified monitoring system which uses an acceleration pickup and analyzes the vibration signal of bridge piers generated with a light hammer. The system is a dynamic system model based monitoring system for the bridge piers.
