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 χi of each granulometric soil fraction extracted in the previous stage is determined; then, on the basis of the obtained deformation characteristics χi 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; Ai - 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: ΣAi=1 (the sum of the proportions (relative content) of individual fractions in the new non-cohesive disperse soil equal to one); χi - 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.
