PROBLEM TO BE SOLVED: To determine soundness of a bridge with a simplified measurement system.SOLUTION: A bridge monitoring system comprises: a plurality of sensor units that are mounted on a mobile body moving on a bridge girder of a bridge in a main girder direction so that the units apart from each other and measure vibration in a predetermined direction at respective mounted positions; and a data formation unit that sets a target position to be evaluated which is an evaluation target position of the bridge, at a specific position in the extending direction of the bridge main girder and extracts time history data within a predetermined time range related to time at which a sensor unit passes through, from each of pieces of time history data measured by the respective sensor units, and creates time history data on a measurement value of vibration at the target position to be evaluated by connecting the extracted pieces of time history data in order according to time series. |
