Sammanfattning

The transmission of vibrations over the surface of the ground, due to a high-speed moving, vertical harmonic strip load, is investigated theoretically. Consequently, the problem is essentially two-dimensional and the interior of the ground is modelled as an elastic half-space. The transformed solutions are obtained using the Fourier transform on the space variable. A study of a new damping model in the spatial wave-number domain is presented in Appendix A. Numerical results for the displacements on the surface are presented for loads moving with speeds up to and beyond the Rayleigh wave speed of the half-space.
