Article presents experience on implementation of geophysical methods on geotechnical monitoring and surveying of building foundation and underlying soils. Studied methods of electric-contact dynamic probing, seismoacoustic sounding and seismic exploration using reflected transversal waves allow to assess changes of state in building structures and soils affected by unfavourable geological processes. Geophysical methods allow to reveal dynamics of changes in soil properties during over the course of geotechnical investigations at the initial stage of construction and at the time of building operation. Application of geophysical methods on a number of buildings at the Vnukovo airport complex studied in the article. The investigations were done on an open-type car-parks located at the airport’s landside and on one of the airport terminals. During investigations, depth of the foundations and their condition, alongside with physical and mechanical properties of the underlying soils, were determined. Structure of underlying soil stratification up to a depth of 40–50 m was studied to detail the structure of the geological cross section, as well as to identify weakened zones that are potentially dangerous for the airport terminal in question. Analysis of the obtained results showed that the most informative way is to use geophysical methods in combination with the results of previously performed surveys, and direct methods for determining the physical and mechanical properties of soils and building materials.
