KRYLOV, V.V., 1999. Ground vibration boom from high-speed trains. Low Frequency Noise, Vibration and Active Control, 18 (4), pp. 207-218.
A brief review is given of the recent theoretical investigations into generation of
ground vibrations by high-speed trains carried out at the Nottingham Trent
University. One of the most interesting results of these investigations was the
prediction of a ground vibration boom from high-speed trains which may occur
when train speeds exceed the velocity of Rayleigh surface waves in the ground.
The existence of a ground vibration boom has been recently confirmed
experimentally on the newly opened high-speed railway line in Sweden for train
speeds of only 160 km/h. The observed very large increase of generated ground
vibrations implies that this phenomenon should be taken into account by
designers and operators of high-speed railways.
