ABSTRACT
Clay liners are commonly used to control the movement of contaminants. Of increasing concern is the influence of salt solutions on the consolidation of clay liners. As a salt solution permeates a clay liner it generates osmotic flows and changes in thickness of the diffuse double layers. These two processes cause volume change and a redistribution of salt throughout the clay liner. Previous analyses of coupled chemical and mechanical consolidation have considered solute diffusion only. This study considers the influence of solute advection on the volume change and solute distribution within a clay liner. It is shown that solute advection can have a large effect on the excess pore water pressures and solute distribution.
