• Resumen

  • The topic of vibration induced by rail traffic has received a special attention from the scientific community over the last decades. Thus, procedures to minimize the discomfort caused by an efficient railway network have to be proposed. In this paper a preliminary numerical study is presented about the mitigation of vibrations based in the introduction in the ground of a set of inclusions parallel to the railway track. Analysis in space-frequency, and frequency-wavenumber domain allowed concluding that the ground wave-propagation is strongly affected by the inclusions presence. Indeed, theoretical simple equations were derived and here proposed in order to allow the engineering tuning of the solution.
