A NUMERICAL GROUND MODEL FOR RAILWAY-INDUCED VIBRATION

A numerical model is presented in this paper for the simulation of vibration from trains on layered soil media. The model rigorously accounts for the infinite lateral extent of the ground. Moreover, it can accommodate the details of the track embankment and the rail. Therefore, this model makes it possible to study the effect of certain counter-vibration screens alongside the track. Both the low-frequency quasi-static vibration due to the moving loads and the high-frequency dynamically-generated vibration can be handled by this model, although in this paper the focus of the results is on the latter. As a practical application of the model, dynamically-generated vibration from a typical train wagon over a ballasted track, with and without a stiffening beam in the railway embankment, is numerically simulated and the effect of the beam in reducing the ground vibration is quantified.
