In the deformation of the fulcrum, which accounts for most of the deformation of the railway steel bridge, it is important for the maintenance and management to understand the tilt of the bridge leading to the crack of the fulcrum. It is thought that if the tilt can be detected by the track equipment monitoring device installed in a part of the commercial train that runs every day, it will lead to efficient maintenance, but the track behavior when tilt occurs and the track condition before and after the bridge The effect of is unknown. Therefore, the purpose of this study is to carry out a running analysis simulation to confirm the effects of the tilt and the track condition before and after the bridge.
