摘要：

Electrical potential, water flux, and hydraulic gradient were studied for saturated water flow through plugs of sodium bentonite at concentrations ranging from 11. 5 to 35. 1% clay. A special permeameter with an adjustable piston allowed measurements to be taken with a given mass of clay, but with successively lower clay concentrations as the piston was shifted out to increase the water content of the clay-water mixture. At the lowest clay content, both electrical potential and water flux increased less than proportionally with increasing hydraulic gradient.
