Abstract

The crucial features for the identification procedure of Green's dynamic function for the displacements on the surface of the soil are considered. The soil is considered as a dissipative linear elastic general half-space having a homogeneous isotropic non-parallel top layer. Green's function is divided into the part that belongs to indirect waves and the part belonging to direct waves which contribute substantially to the amplitude of the displacements. Very efficient exponential approximating functions are proposed for the direct waves, along with complex Proni's computational method that solves the inverse problem. Considering the data that the measurements yield and the spatial dependent functions needed in interaction analysis, we solved the problem of the interpolation and the extrapolation of the band l
