Vibrations that are excited by moving trains inside a tunnel are regularly transmitted via the tunnel and the surrounding soil and often perceived at the surface. In order to assess the effects of the arising vibrations and to be able to model possible mitigation measures, a suitable model of the system is necessary. In this paper, a coupled approach is presented, where the emission system of an underground tunnel is modeled using the Finite Element Method while the transmission medium of the soil is described by Integral Transform Methods.
