Authors: Башилов И. П., Верещагин А .А., Загорский Л. С. и др. 

The article discusses application of the passive seismic method MOVSR by the single channel seismic sounding technology (SCSS) using the software/hardware single channel seismic station in geological engineering survey on the Mikhnevo test ground of of the Institute of Geosphere Dynamics, Russian Academy of Sciences. The specifications of the sing channel seismic station, field operation technology, mathematical calculation algorithm and its results in the form of the velocity profile plot are described. The technology SCSS features simplicity and operational efficiency. Its implementation needs 3 seismic detectors. Two detectors are installed at a distance from the test site and serve as the reference stations which operate continuously and are used to eliminate temporal variations. The third movable seismic detector is used to obtained data at the test point. The simultaneous operation of two reference detectors accelerates field works. A feature of the data processing procedure is the calculation of the Fourier transform by the coordinate along the profile and the use of the almost periodic functions at resonance frequencies. The calculations revealed deceleration of SV-component of the Rayleigh wave due to the presence of a vertical shaft and two adits in the test ground. The capabilities of the method are illustrated from the comparison with the borehole data obtained nearby the Mikhnevo settlement. It is concluded on applicability of the software/hardware single channel seismic station with the single channel seismic sounding technology in geological engineering surveys.

Keywords: MOVSR, single channel seismic sounding technology, software/hardware single channel seismic station, seismic detectors, passive seismic, velocity profile, geological engineering surveys, almost periodic functions.
