This paper presents a three-dimensional semi-analytical approach to study the displacements induced by harmonic loads moving at constant speed over the surface of a poroviscoelastic multilayered half-space. The load distribution is considered either as a rectangular load moving straight over the soil or moving on a beam resting on the ground. The displacements in the wavenumber domain are expressed in terms of incident and reflected waves in each layer. An assembly process is used to deal with the multilayered system. Numerical results for both sub- and super-Rayleigh regimes are presented in the wavenumber and spatial domains. (C) 2010 Civil-Comp Ltd and Elsevier Ltd. All rights reserved.
