This invention discloses a method for railway safety assessment under time-varying effects throughout the construction process of a railway-related T-shaped rotating bridge. This method divides the entire construction process of a railway-related T-shaped rotating bridge into three analysis stages: bridge completion process analysis, bridge rotation motion analysis, and bridge operation status analysis. In the bridge completion process analysis, a coupled analysis model of the bridge completion process and the railway is established to consider the impact of the bridge completion process on the railway. In the bridge rotation motion analysis, a refined analysis model of the bridge is first established to analyze the maximum deformation of the piers during three transient states: rotation start-up, uniform motion, and rotation braking. Then, the maximum deformation of the piers is applied to an equivalent coupled analysis model to achieve a refined analysis of the impact of the entire bridge rotation process on the existing railway. In the bridge operation status analysis, a coupled analysis model of the bridge operation status and the railway is established to consider the impact of the bridge operation process on the railway. In summary, this method can achieve railway safety assessment under time-varying effects throughout the construction process of a railway-related T-shaped rotating bridge.
