Study of the deformation characteristics of soils with a change in humidity

This paper discusses the anisotropic properties of soils and the issue of the influence of soil wetness on the stress-strain state of an anisotropic foundation. The study of material properties and the nature of these properties is directly related to the origin and structure of the object under study. The most important of them from the point of view of calculations of foundations, design of buildings, and structures are deformation, strength, and filtration anisotropy, which introduce changes to a greater or lesser extent in the stress-strain state of soil massifs. The entire set of physical and mathematical properties of soils is determined by their structure and texture, which, in turn, are formed depending on the composition and genesis of soil deposits, as well as under the influence of external factors leading to the transformation of the stress state of the soil mass. Practically in all experiments in which the deformation, filtration, strength, and other properties of soils were studied in various directions, a difference in their indicators was noted. Such results testify to the anisotropic manifestation of these properties. An elastic (linearly deformable) soil model is considered a design model of soils that make up an anisotropic base.
