Description
Summary:Modern construction is developing at enormous speed, which leads to the need for more in-depth study of the physical and mechanical properties of soils in general, and clay soils in particular, in order to make rational use of their natural properties in the construction and design of foundations, foundations and soil structures. In this regard, recently, special attention has been paid to the study of the rheological properties of soils. One of the main rheological parameters of the soil is its viscosity. To determine the coefficient of viscosity of the soil in this study, a simple shear device was used. An artificially created sandy loam consisting of fine quartz sand (60% by weight) and clay particles (40% by weight) was adopted as the test soil. In the course of the study, characteristic graphs of the dependence of tangential stresses on shear deformation at different test speeds were obtained. Also, taking the Newton equation as a basis, the average value of the soil viscosity coefficient was determined for each shear rate.
