Influence of Ballast Mats on the Reduction of Track-ground Vibrations Induced by Railway Traffic
This paper presents a numerical study developed in order to understand the dynamic be -haviour of ballasted tracks with mats including the train -track-ground interaction. In order to achieve that goal,a case study is modelled by a 2.5D FEM-BEM formulation. The comparison between isolated and non isolated scenarios allowed concluding that the ballast mat has a dual effect , focusing on the train-track dynamic behaviour and on the reduction of high -frequency vibrations that are transmitted to the ground.
