instrumental engineering and seismological inspection of physical state of buildings and structures by measurement of microvibrations of object under action of microseismic background. SUBSTANCE: family of three-component vibration transmitters periodically moved in sequence and three-component vibration transmitter located in fixed reference point are used for simultaneous measurement of vibrations of object. By way of re-computation of recordings of family of movable vibration transmitters reduced to common registration time and to corresponding level of microvibrations in reference point recordings of measurement signals reduced to common time of registration for any number of observation points on object with the aid of limited number of transmitters and recording equipment are obtained. EFFECT: possibility of presentation of three- dimensional vibrations of object equivalent to simultaneous multichannel registration in same points on object. 20 dwg
