| The subject of the project is the design and verification of transition area structures between the railway superstructure structures and the railway substructure objects as places of significant change in track stiffness. By applying numerical modeling and experimental analysis methods, the expected maximum load values at the individual interfaces of the structural layers of the proposed transition areas will be obtained, for various cases of the railway superstructure structure (classical and unconventional), railway substructure objects (bridges, culverts, underpasses, tunnels) and various structural compositions of the transition areas (modification of structural elements of the track grid and materials of the structural layers of the railway substructure) with regard to maintaining the required deformation resistance of the railway track structure during its service life. Verification of selected transition area designs will be carried out by experimental measurements of stress in individual structural layers and by monitoring the track geometry in the entire area of interest of selected modernized track sections. |
