WebThe constant head permeability test is a laboratory experiment conducted to determine the permeability of soil. The soils that are suitable for this tests are sand and gravels. Soils with silt content cannot be tested with this method.The test can be employed to test granular soils either reconstituted or disturbed. Objective and Scope WebIn this paper, laboratory tests are conducted to investigate the eect of clay content on behavior of permeability for artificial argillaceous sandstone samples under stress dependence. Then a corresponding theoretical model for stress dependent permeability of APM based on fractal theory is derived to interpret the experimental results.
