CALCULATION OF THE BALLAST RESISTANCE TO TRANSVERSE DISPLACEMENTS OF SLEEPERS DURING HIGH-SPEED TRAIN MOVEMENT

Abstract

Based on the generalization of experimental data, an algorithm for calculating the resistance of the ballast to the transverse displacements of the sleeper under the action of vertical and lateral loads is developed. One of the factors that counteract the deformations of the rail-sleeper grid in the horizontal plane is the resistance of the ballast to the shear of the sleepers. The quasi-static forces of the resistance of crushed stone ballast to the displacement of a sleeper with a concave support part and a geotextile gasket from the shear value and vertical load are determined. As well as determining the energy dissipation in various elements of the track structure by the shift of the operated track, at which the energy dissipation coefficients for the movements of the rail head, lining and sleeper from the load on the rail were determined.
