Ground vibration induced along a railway line by train running varies in
complex ways according to the condition of the vehicle, its axle load or
axle arrangement for example, plus the track, structures, and the ground
and other ground level conditions. This means that it is important to clarify
how these various conditions impact ground vibration in order to predict
ground vibration and study effective countermeasures. The RTRI has, therefore,
developed a ground vibration simulation method that can be used to quantitatively
evaluate the impact of vehicle and ground conditions on ground vibration.
This simulation method can be applied to predict ground vibration under
varying vehicle, track, and structure conditions. It can also quantitatively
evaluate the effectiveness of vibration countermeasures applied to vehicles
or to tracks.
