|Abstract: ||Railway-induced ground vibrations may cause noticeable movements of nearby buildings that
result in damage or disamenity, both directly and by generating structure-borne noise. Both
effects depend strongly on the spectra of railway-induced ground vibrations that, in turn, are
determined by the contributions of differenl excitation mechanisms and by soil properties.
Spectra of railway-induced ground vibrations, including train-speed dependent components,
have been studied experimentally, and qualitative analysis of the quasi-static excitation
mechanism has been attempted. However, no rigorous theoretical investigations of railway generated
ground vibrations have been carried out and no quantitatively calculated spectra exist in
In this paper we consider theoretically the effect of quasi-static pressure of wheel axles onto
the track-soil system. In the case of welded rails and perfect wheels, this mechanism is the major
contributor to trainspeed-dependent components of the low-frequency vibration spectra (up to 50
Hz), including the so called passage frequency fp = v/d, where v is train speed and d is distance
