Theoretical Issues with Rayleigh Surface Waves and Geoelectrical Method Used for the Inversion of Near Surface Geophysical Structure

We numerically simulate the field measurements of Rayleigh surface waves and electrical resistivity in which target depth is set to be less than 50-m. The are simulated terms fundamental mode group phase velocities. seismic data assumed collected through a conventional shot-gather. velocities found from application multiple filter technique single-station fashion while for slant stacking, or linear radon transform applied multichannel analysis (MASW). average structure source receiver (or geophone) represented by velocity curve underneath geophone array curve. curves transformed into local setting system grid points. shear-wave cross section examined area constructed inverting these curves. underground similarly studied. compilation completed electrode Pole-Pole array. actual assemble analyzed inverted considering apparent (measured) values. Unique forms such as ore body, cavity, sinkhole, melt, salt, fluid within Earth may joint interpretation resistivities These formations better outlined following their distinct signs high/low Doi: 10.28991/HEF-2021-02-03-01 Full Text: PDF
