  • Recognition of karst structure using refraction tomography

    The results of location of karst wells and probable hydraulic connections between them in limestone massif using the refraction tomography are presented. Seismic modeling was based on refraction horizon recognition in the first stage and tomographic processing of P-wave and S-wave velocity changes in the second one. The studies were carried out on the terrain neighboring to the wall of abandoned ...

  • Three–dimensional seismic tomography with tetrahedra element on isoparametric mapping

    The author has developed a method of three–dimensional seismic tomography on concrete structures. This method is based on ray–trace and identification technique, and the distribution of slowness or energy dissipation is identified based on simultaneously iterative reconstruction technique (SIRT) or the other kind of statistical identification technique. This kind of technique was originally ...
