Abstract
The railway track superstructure undertakes the forces that develop during train movement and distributes them towards its seating. The track panel (sleepers with their fastenings or slab with the fastenings) plays a key role in terms of load distribution, while at the same time it ensures the stability of the geometrical distance between the rails. Earthworks and ballast (if it exists) undergo residual deformations, settlements and lateral displacements, directly influencing the deterioration of the so-called geometry of the track, which can be nevertheless described much more specifically as quality of the track. In this paper, a parametric investigation of the stiffness of the substructure of the railway track and of the elastic pads of the fastenings is presented. Moreover, conclusions are drawn for the magnitude of the acting forces. A methodology is also suggested for the calculation of the actions and stresses that strain the layers of the track structure as well as for the mean pressure on the seating surface of the sleepers (or the slab) and the total settlement of the structure.
