Abstract
Summary
This article is devoted to the assessment of physical and mechanical properties of soils subjected to deep-frozen, seismic-acoustic tomography in construction metro's. Complex engineering-geological conditions of the territory of St. Petersburg suggest the use of the underground construction method of artificial freezing soils'. The system of paleovalleys, folded moist unstable sand-clay deposits are a complicating factor in the construction of the subway.
