Abstract
In this paper, a parametric investigation of the static and dynamic elasticity (stiffness coefficient) of the railway track and of the elastic pads of the fastenings is presented for the cases of Ballastless Track (Slab Track and Embedded Track), Transition Zone and Ballasted Track. Moreover, the influence of the variation of the static and dynamic elasticity on the acting forces on the track superstructure and substructure is investigated, a factor that is of decisive importance for the design of the Track layers and conclusions are drawn for the magnitude of the acting forces and of the mean pressure on formation in comparison to the permissible compressive stress. A methodology is also suggested for the calculation of the actions and stresses that strain the formation of the track structure.
