Conclusions 1. The construction of compacted soil beds makes it possible to eliminate the collapsibility properties of soils in the bases of buildings and structures to a depth of 8–12 m. The dry density of the soil in the compacted soil mass was 1.73–1.80 tons/m3. 2. In the upper part of the soil bed, to a depth of 1.0-1-3 m a decompressed soil layer with γd=1.35–1.55 tons/m3 is formed, which must be additionally compacted with heavy rammers. 3. The moduli of deformation of the soils at the tamped soil bed in the pressure range 0–4 MPa are 18–21 MPa. 4. To prevent bulging out at the soil to the surface, tamping of the material at the face and filling of the trench hollow must be carried out to a "refusal" equal to 10 cm per blow. 5. Use of tamped soil beds is recommended for buildings with on equivalent pressure equal to or exceeding 0.1 MPa in collapsible soils with 1.6≥γd≥1.4 tons/m3 and in fill soils with γd≤1.6 tons/m3. The corresponding natural water content of the soil should be in the range wp+0.04≥w≥wp−0.04.
