FIELD: construction.
SUBSTANCE: method for laboratory determination of rheological characteristics of soils includes detection of deformation characteristics of undisturbed or disturbed soil under conditions of uniaxial compression without possibility of its side expansion in a compression device in the mode of stresses relaxation, and a compression curve is built by final values of stresses and their appropriate deformations of the sample as each stage is completed. For each of relaxation branches they build curves of deformation dependence on deformation speed. Then points are market on these curves with selected values of sample deformation speeds, their appropriate values of deformations are applied onto relaxation branches, and a bundle of curves is pulled through them, as corresponding to selected values of deformation speeds. Using these curves, they determine values of deformations corresponding to the selected value of the vertical load, and on the basis of this data they build curves of deformation dependence on time, by which they determine coefficients of filtration and secondary consolidation with available methods.
EFFECT: reduced terms and labour inputs for performance of laboratory tests for determination of rheological characteristics of soils, including detection of coefficients of filtration and secondary consolidation.
