Now at construction in areas of distribution of "weak" soil (clays and loams which differ in different degree of a peat and also peat) this soil is key at adoption of design decisions. These circumstances for Krasnodar allowed to generalize the received information on engineering-geological properties of the bearing soil, to work out the equations for calculation of parameters of consolidation for other properties of soil. In total about 200 results of laboratory researches of physicomechanical properties of soil were processed. By means of the statistical device dependences between "standard" physicomechanical and consolidation characteristics of soil are found. Series of schedules of dependences are constructed. On the basis of the analysis of multiple regressions the equations for calculation of parameters of consolidation for other properties of soil are worked out. The importance and possibility of application of these formulas are confirmed with statistical processing of the received values. Use of the offered formulas allows estimating consolidation properties the peat soil of clay soil of the studied territory.
