Conclusions
1. The compressibility of sandy permafrost deep deposits with a medium texture density is, as a rule, close to the compressibility of similar thawed deposits.
2. The degree of saturation of frozen sandy soils may serve as an indicator of their compressibility during thawing. When Gf<0.91, the compressibility of frozen sands during thawing is equal to the compressibility of similar thawed soils.
3. The compressibility of frozen sandy deposits during thawing, which increased as compared with ordinary thawed sands, should be expected in zones adjacent to the roof of soils with a low permeability.
4. The refinement of the method and the high quality of the testing of thawing soils increases significantly the technicoeconomic effectiveness of construction on permanently frozen sandy soils, making it possible to reduce the volume of special measures taken to ensure the stability of buildings and structures, or eliminate them entirely.
