ABSTRACT

In recent years, geosynthetic Clay liners (GCLs) are widely used in different kinds of anti-seep-age projects and the anti-seepage availabilities of GCLs are regarded as increasingly important by engineers. Anti-seepage effectiveness of GCLs involves at least two aspects, such as Hydraulic conductivity of GCLs under engi-neering practice conditions, and Absorption ability of bentonite in GCLs in the course of liq-uid permeation. In this paper, Hydraulic con-ductivity tests are performed to obtain seepage coefficient of GCLs, taking liquids such as dis-tilled, deioned water and landfill leachate, and solutions with single-species cation as the hy-dration and permeation liquid. The results Show that cation valence, cation concentration and hydration ionic radius in hydration and permea-tion liquids have influences on hydraulic con-ductivity of GCLs.
