Abstract

Abstract: In order to find out the damages of the station structures timely to ensure structural safety to the greatest extent, an overview of health monitoring on railway station structures, including canopy without platform columns, roof structures, elevated layer and bearing rail layer were presented, problems of sensor layout, structural damage identification and early warning threshold in the passenger station structural health monitoring were analyzed, identification methods of structural damage was introduced and suggestions in the aspects of structural construction, operation and maintenance were put forward.The results show that damage identification method suitable for railway station should be studied based on existed methods, operating environment and structural features.Optimized arrangement of sensors should also consider operational requirements of construction. Information sharing between construction and operation departments should be strengthened so as to form a long-term and effective monitoring and management mechanism of railway passenger station structure health.

Key words: railway station, structural safety, health monitoring, sensor, damage identification
