Grading modulus of soil formula
Did you know?
In soil science, 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 conductivity. In a design, the gradation of the in situ (on site) soil often controls the design and ground water drainage of the site. A poorly grad… WebThe Modulus of Subgrade Reaction is a measure of a soils stiffness. It is an indicator of a soils resultant unit displacement under a given pressure. The units of Modulus of …
