METHOD OF DETERMINING PHYSICAL PROPERTIES OF SOILS Russian patent published in 2016 - IPC G01N33/24 G01N9/00 

FIELD: geology.

SUBSTANCE: invention relates to engineering geology with respect to determination of required soil parameters. Method involves collecting soil sample, weighing and determination of its volume, drying and weighing of a dried sample, determination of density and moisture content of soil sample and calculation of obtained values of density and soil moisture content, wherein curves are plotted of relative air content in soil and degree of filling pores thawed soil water and ice from frozen soil moisture at various permanent soil density values, calculation data for plotting curves is performed in two points at zero total humidity of thawed or frozen soil and at zero relative air content in a sample of soil from given relationships for thawed and frozen soil. Then experimentally found values of density of dry soil and soil humidity from curves are used to determine relative air content in a sample of soil in thawed and frozen conditions, soil porosity, total moisture-retention capacity of soil sample in thawed and frozen state and degree of filling pores in thawed soil sample State-water and frozen state-ice, for this purpose from a point on abscissa corresponding to experimentally found value of total moisture content, a vertical line is drawn to intersection with inclined straight relative air content in a sample of soil in thawed and frozen states of total moisture content and degree of filling ground water or ice from the total moisture content, ordinate intersection points of which are equal values of relative air content in a sample of soil and degree of filling pores of soil sample in thawed and frozen conditions, and intersection of inclined forward relative air content in a sample of soil in thawed and frozen states of total moisture content with ordinate axis provide value of porosity of soil sample, and on abscissa axis-full its moisture capacity in thawed and frozen conditions.

EFFECT: higher efficiency of determination.
