✦ Synopsis

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.

A sequence of results is presented from a model of an oscillating load moving on a track on a layered ground. The results allow a visualization of the e!ect of the relative speeds of the load and the propagation speeds in the ground structure. This is useful in developing the understanding of the in

The transmission of vibrations in the vicinity of a rectangular harmonic vertical load, acting on a viscoelastic layer overlaying a rigid half-space, is investigated theoretically, using a semi-analytic approach. The solution involves a double Fourier transform with respect to two of the space varia
