TL;DR: In this paper, the authors present some vibration measurements collected on a Belgian site located between Brussels and Paris/London and travelled by the Thalys and Eurostar high-speed trains, and compare them with the results obtained by a recently developed model, involving the compound vehicle/track/soil system.

TL;DR: A full three-dimensional FEA for the prediction of railway ground-borne vibrations and investigations with commercial FEA software ABAQUS are presented, with the development of an external meshing tool so as to automatically define the infinite elements at the model boundary.

TL;DR: In this paper, the corrected development of viscous boundary efficiency initially proposed by Lysmer and Kuhlemeyer is presented, and the expressions of the energy ratio are given, in accordance with the original numerical results, and confirm the authors' recommendations to minimize the reflected energy of body waves that impinge on the artificial boundary.

TL;DR: In this article, a coupled lumped mass model (CLM) is proposed for the vertical dynamic coupling of railway track through the soil, which is based on the well-known Winkler model and its extensions.

TL;DR: In this article, the authors investigate the generation and propagation of ground vibrations induced by railway traffic, more specifically in the case of urban vehicles, using an uncoupled approach: the vehicle-track subsystem is first simulated to provide the ground forces which, in turn, are applied to the model of the soil.
