The IZIIS’ Laboratory for Geophysical Surveys consists of equipment and instruments for realization of different investigations in the field of engineering seismology, engineering geophysics, geotechnics and other fields. At the moment, the following equipment is available at this laboratory:
SoilSpy Rosina, 33 channel digital seismograph, MOHO, Italy. It is used for investigations by use of the following methods:
- Investigations based on analysis of propagation of P- and S- seismic waves: seismic refraction (conventional and tomographic approach) and seismic reflection.
- Surface wave methods: passive (fk, SPAC, passive MASW, REMI) and active methods (MASW, SASW) based on dispersion characteristics of surface waves.
AKULA -9000C – Multi-channel georadar (up to 16 channels) compatible with antennas with central frequency of 10-4000 MHz.
GCB-300 – Ground coupled antenna with central frequency of 307 MHz for investigations performed down to the depth of 8 m.
GCB-1000 – Ground coupled antenna with central frequency of 1000 MHz for investigations performed down to the depth of 1.5 m.
GEKKO-60-SR – Airborne antenna with central frequency of 65 MHz for investigations performed down to the depth of 30-50 m.
TROMINO® (5) – 3-component seismometer, MOHO, Italy. It is used for investigations performed by use of the following methods:
- H/V technique: Computation of Vs30 by modeling a H/V curve.
- Investigations by application of 2D seismic arrays for Vs modeling of soil.
