MATHEMATICAL MODELING OF THE PROCESSES OF DEFORMATION OF SOILS WITH TIMED. I. Zolotarevskaya UDC 539.376:631.43:001.573 It has been suggested that the rheological properties of soils be modeled by the integral Volterra equation of the second kind of the nonlinear heredity theory and by the differential equation which, under certain conditions, approximately replaces the adopted integral equation. Parameters of these governing equations have been found from experimental data for a number of soils. The processes of creep of soils have been studied. K. A.
