WebThe permeability of both clay-rich and non-clay gouges, as well as several pure clays, was studied as a func- tion of confining pressures from 5 to 200 MPa and shear strain to 10. Permeability ranged over four orders of magnitude, from around 10 -22 to 10 -18 m 2 (1 darcy = 0.987 x 10 -12 m2). The lowest values were charac- WebJun 19, 2016 · For an equitable comparison, the Champlain sea clay of Louiseville [] was chosen as the example in our studies, which Sun et al. [] used in their studies as well.Firstly, the measured value (, m 2), which is the largest void ratio and the corresponding permeability tested in the reference, was used as the initial data point; these allowed the …

WebPermeability, as the name implies (ability to permeate), is a measure of how easily a fluid can flow through a porous medium. In geotechnical engineering, the porous medium is soils and the fluid is water at ambient temperature. Generally, coarser the soil grains, larger the voids and larger the permeability.
