Monitoring of steel railway bridge and continuous welded rail
Original language description
The continuous welded rail (CWR) is standardly used on almost all modern railway bridges. However, its placement results in the interaction between CWR and the structure. That brings not only the longitudinal forces on the substructure, but also a significant additional stresses in the rail. These stresses can result either to the rail brak, or track buckling. Unfortunately, the input parameters for performing numerical analysis are hardly accessible and they vary significantly in different sources. Because of that, the extensive long-time monitoring of the rail-bridge interaction was performed on the bridge with the unusual combination of ballast track, direct fastening and barrier in the ballast. The paper presents the results of the monitoring and comes with the analysis and evaluation of formulas, defining the fastening nonlinear stiffness of track to bridge connection. The influence of the temperature to the ballast stiffness is analysed as well.
