  • Soil gradation Wikipedia

    Soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility, shear strength, and hydraulic.

    Both the position and the shape of the grading curve for a soil can aid its identity and description. Some typical grading curves are shown in the figure: A - a poorly-graded medium SAND (probably estuarine or flood-plain alluvium) B - a well-graded GRAVEL-SAND (i.e. equal amounts of gravel and sand) C - a gap-graded COBBLES-SAND.
