The wave propagation on the surface of a half-space due to a moving load is
analyzed using the Integral Transform Method. By using of the Helmholtz’s decomposition
and threefold Fourier transformation the body wave equation is transformed in the wave
number-frequency domain and solved numerically. The obtained displacement field is
transformed in time domain by the Inverse Fourier Transform. The analysis is carried out
using computer program written in MATLAB program language. The load is vertical
sinusoidal force P=1 MN moving along the line defined by x=0 with constant speed. The
influence of source velocity on the displacements of the half-space and on the frequency
content of the displacements at three locations at different distances from the load line is
presented.
