DEPENDENCE OF THE STRENGTH AND DEFORMATION CHARACTERISTICS OF SILTY CLAY SOILS ON THE YIELD INDEX.

Abstract

With the massive nature of intensive modern construction, it is necessary to quickly determine the physical and mechanical properties of soils. However, due to the need to perform and conduct engineering and geological surveys in a short time when obtaining design characteristics with a small number of studies, errors largely occur, despite the fact that the error can lead to both overestimation of the calculated characteristics and underestimation, especially of dusty clay soils, since laboratory tests of such soils are longer than others. Silty-clay soils often depend on the composition and content of water in them. In addition, it should be noted that such characteristics as soil moisture, consistency change significantly even within the same studied stratum. Soil moisture has a significant impact on the way the soil is excavated and on the ability of soils to compact. Correlation analysis of dependencies was carried out on the basis of technical reports on engineering and geological surveys carried out by various organizations in the territory of Pavlodar. In the course of the research, dependency equations were obtained that allow expanding the range for faster determination of the mechanical characteristics of pulverized clay soils.
