ABSTRACT
The extension of high-speed train connections through densely populated urban areas and between city centers together with the increase of train speed require not only control of the rail-track dynamics but also the propagation of vibrations in the subsoil and into building. Wave propagation and vibration reduction are recently described and treated by theoreticians and are measured at several locations in Europe. This paper will give an overview of several locations where track displacements are a risk. Based upon the measurements finite element models have been used to compute track displacements of high-speed trains. The computations are used to design track sections with vibration reduction measures to diminish dynamic amplification of a track.
