Numerical modeling of the tamping operation by Discrete Element Approach

Abstract

Ballasted tracks have been widely used because of their flexibility from the point of view of construction and maintenance. The deterioration of the railway track under heavy train traffics induces various irregularities in the track mainly due to differential settlement. In order to restore the initial geometry of the track, the ballast tamping operation is currently in use. In this work, we focused on the influence of tamping on ballast compaction by means of three-dimensional Discrete Element Method (DEM) simulations.
