On the establishment of the correlation dependence of results of physical properties, dynamic probing and filtration coefficient from the granulometric composition of alluvial sands in the valley of the Amudarya river

Abstract

Based on the study of the mechanical composition and physical properties of alluvial sands, the correlation equation necessary for engineering and geological studies to analyze the lithological conditions of the soils, the average physical properties of the Amudarya river and soils, and the average number of strokes per 1 dm immersion probe are studied. Quantities of definitions are represented in large numbers. The study of the physical properties of the sand of both terraces is complicated by the very close occurrence of the groundwater level. Above and near the groundwater level, physical properties were studied in pits, some of which were drilled. Samples of undisturbed sand were taken with a 700 cm3 cutting cylinder. The volumetric weight of the skeleton of both terraces in natural addition is the same for species with the same particle size distribution (1.30-1.50 g / cm3). The geological structure was studied in wells that were drilled by a rope method. Samples were taken from these wells to determine the particle size distribution of the sand. The mineral composition of sand and clay determines the nature of their resistance to shear, and clay soils are characterized by resistance to uniaxial compression and rupture.
