Measuring Effects of Permeant Composition on Pore-Fluid Movement in Soil

Source

A laboratory experimental system is described for measuring the effects of permeant composition on pore-fluid movement in a soil specimen mounted in a conventional triaxial cell. These effects include the variation of permeability that arises when the pore-fluid composition changes within a soil, and also the tendency for a permeant composition gradient to cause pore-fluid movement. The system is based on the previously reported capabilities and advantages of the flow-pump method for permeability measurements. The system also utilizes a permeant-control subsystem that facilitates bringing deaired solutions of arbitrary chemical composition from storage reservoirs to the ends of a test specimen.
