Abstract. When designing foundation of buildings and structures, it is necessary to select such economical and reliable design solutions which ensure the most complete use of strength and deformation characteristics of soils. Often the true values of physical-mechanical characteristics of soils are presented in the reports on engineering surveys in overstated or understated form that leads to the most complex or vice versa simplified design solutions for foundations. At this, the main disadvantage is the incorrect definition of soil deformation properties, the deformation modulus especially. The results of experimental studies of deformability characteristics of weak water-saturated clayey soils under the laboratory, field, and natural conditions are presented. It is shown that the definition of deformation characteristics of various kinds of soils should be made with due regard for their specific properties since there are differences between the results of laboratory tests in compression devices and research In deformation characteristics of soils which are determined under the natural conditions with the use of the stamps of 600 and 3000 cm2. It is established that under the natural conditions in the layers of weak water-saturated clayey soils there is a constant pore pressure which should be taken into account when calculating foundations of industrial structures by limit deformations. The study of pore pressure in the thicknesses of weak water-saturated clayey soils shows that its value can be used when determining strength and deformation characteristics of this kind of soil.
Key words: characteristics of soil deformability, weak water-saturated clayey soils, deformation modulus, pore pressure. - REFERENCES
