Abstract
A method is substantiated for calculating the vertical seismic profile using Rayleigh polarization waves recorded on the surface, which occur during the interaction of P and SV waves localized in the heterogeneous half-space. The method makes it possible to solve the inverse problem of finding the velocities of longitudinal and transverse waves in the massif with the number of calculated points achieving 400. An algorithm of the method is presented which envisages application of multimode dispersion analysis and computation of reference points for the wave velocity in B.M. Levitan algebraic polynomials. The possibilities of the method are illustrated by examples of using it to study model objects, as well as by results of comparing microseismic exploration data.
