Abstract. Saving of expensive materials in foundation construction makes engineers to design foundation slabs of different thickness in differently loaded parts of the building. The resulting morphometry of the base plate sole can lead to the formation of "traps" of hydrostatic pressure when forming the man-made aquifer within the area of the pit. On a concrete example of construction, the article considers the engineering-geological and hydrogeological conditions that lead to the formation of anthropogenic aquifer directly under the foundation slab under the condition of local distribution of the upper water mainly in the clay soils of the base. The methods of elimination of the base plate emersion are proposed and it is shown that when projecting it is required to take into account not only economic indicators, but also the features of engineering-geological and hydrogeological conditions, soil properties and the forecast of their changes. It is noted that when making design decisions according to the "white bath" technology, additional measures should be developed to eliminate infiltration of underground and surface water into the decompressed soils of cavities of the underground part of buildings and structures.
Key words: foundation slab, clay soils of the base, anthropogenic aquifer of underground water, hydrostatic pressure, engineering-geological conditions. - REFERENCES
