Clay permeability test
WebIntroduction. Soil consolidation refers to the process by which the volume of a partially or fully saturated soil decreases due to an applied stress. When a load is applied to a low permeability soil, it is initially carried by the water that exists in the porous saturated soil and result in a rapid increase of pore water pressure. WebNov 19, 2024 · The permeability coefficients of specimens with different mass ratios were measured under different pressure differences, and the test results showed that the permeability coefficients of the specimens varied in the range of 10 −5 –10 −7 cm/s, which was consistent with that of natural soft clay. During the test, the change of permeability ...
