Title:
BRIDGE DEFLECTION MEASURING METHOD, BRIDGE DEFLECTION MEASURING DEVICE, AND BRIDGE DEFLECTION MEASURING PROGRAM
Document Type and Number:
Japanese Patent JP2023009905
Kind Code:
A
Abstract:
To provide a bridge deflection measuring method capable of easily measuring the deflection of a bridge from a moving body side moving on the bridge, its deflection measuring device, and a bridge deflection measuring program.SOLUTION: A deflection measurement method #100 is a method of measuring the deflection of a bridge on which a train moves, and calculates the deflection of the bridge based on the measurement result of a track displacement measurement device that measures the track displacement on the bridge. The track displacement measuring device measures the passage displacement in front of and behind the train. A deflection calculation process #120 calculates the bridge deflection based on the measurement result of the track displacement measuring device in front of the train and the measurement result of the track displacement measuring device behind the train. The track displacement measuring device measures track displacement at a load position where a train applies a load to a bridge. The deflection calculation process #120 calculates the bridge deflection based on the difference between the track displacement measured by the track displacement measuring device in front of the train and the track displacement measured by the track displacement measuring device behind the train.SELECTED DRAWING: Figure 8
