The purpose of this study is to develop a U-shaped 3-segment long-span (over 25 m) temporary bridge that can be rapidly restored to a railway bridge, and to minimize traffic control and social and economic damage to citizens by utilizing it. The purpose is to develop a temporary bridge that can minimize traffic control in cases where rapid replacement is required due to aging of a railway bridge or a disaster or catastrophe. For this purpose, the detailed design was completed according to the structural review, and the vibration safety evaluation was analytically reviewed. When designing a bridge, various load conditions, irregularities, and dynamic characteristics of the bridge structure and the running vehicle should be reviewed. In this study, the dynamic safety evaluation for various train loads and environments was analytically reviewed, and the applicability and safety of the temporary bridge for the railway bridge under development were reviewed.
