ENGINEERING CLASSIFICATION AND DESCRIPTION OF SOIL

WebThis is called poorly graded soil. Curve II represents a soil in which the particles are distributed over a wide range, termed well graded. A well graded soil will have a uniformity coefficient greater than about 4 for gravels and 6 for sands, and a coefficient of gradation between 1 and 3 (for gravels and sands). Soil gradation is a classification of the particle size distribution of a soil. Coarse-grained soils, mainly gravels or sands, are graded as either well graded or poorly graded. Poorly graded soils are further divided into uniformly-graded or gap-graded soils. Fine-grained soils, mainly silts and clays, are classified according to their Atterberg limits. A well-graded soil is a soil that contains particles of a wide range of sizes and has a good repres… bits pilani cse total fees https://frenchtouchupholstery.com
