Modelling of Train Induced Vibration

This paper reports on recent developments in techniques for modelling ground vibration from railways. The modelling considers both surface and underground railways, and accounts for the main dynamic systems involved, i.e. tracks (both ballasted and slab), tunnels and multi-layered ground. Results are presented to illustrate the modelling capabilities and the efficiency of computations for the models proposed. The work presented is part of the MOTIV project (Modelling of Train Induced Vibration), which is a collaboration between the Universities of Southampton and Cambridge. Future development of models and plans within the project are also addressed.
