METHOD FOR REGULATING DEFORMATION PROPERTIES OF NON-COHESIVE DISPERSED SOIL Russian patent published in 2017 - IPC E02D1/02 

FIELD: construction.

SUBSTANCE: method for regulating the deformation properties of non-cohesive dispersed soil, in which the soil is initially divided into fractions by means of sieves, the deformation characteristic χ_i of each granulometric soil fraction extracted in the previous stage is determined; then, on the basis of the obtained deformation characteristics χ_i of each granulometric soil, the relative content (fraction) A of each granulometric fraction in a new non-cohesive dispersed soil with the required deformation characteristic χΣ so as to fulfill the condition: where χΣ is the required deformation characteristic of the new disintegrated dispersed soil; A_i - the relative content (fraction) of the i-th granulometric fraction in the new non-cohesive disperse soil with the required deformation characteristic is determined by selection so as to fulfill the condition: ΣA_i=1 (the sum of the proportions (relative content) of individual fractions in the new non-cohesive disperse soil equal to one); χ_i - deformation characteristics of the i-th granulometric soil fraction.

EFFECT: reducing labour intensity and material consumption for determining the deformation properties of non-cohesive dispersed soil.
