Abstract
This article discusses determining foundation settlements taking into account the creep of quasi-single-phase and two-phase soil systems of the bases. There is presented distribution of clay soils in depth in the territory of Central Kazakhstan. The analysis of the stratification results shows that physical properties of clays are heterogeneous and have sufficiently large scattering of values in depth. It has been experimentally established that clay soils selected at different depths are characterized by shear decaying creep. Methods of determining the coefficients of consolidation and creep, the deformation modulus from experimental curves are described. The calculationformulas are given for determining quasi-single-phase and two-phase soil systems taking into account their creep. The calculation formulas obtained on the basis of the results of experimental data indicate the novelty of the method.
