EFFECTS OF ELECTROKINETIC PHENOMENA ON SOIL STABILIZATION

A FUNDAMENTAL APPROACH TO THE PHENOMENON OF SOIL CONSOLIDATION BY APPLICATION OF AN ELECTRIC CURRENT IS PRESENTED. A THEORETICAL EQUATION IS GIVEN, WHICH RELATES THE DEGREE OF SETTLEMENT WITH THE ELECTRICAL CONDITIONS. THE EQUATION IS DERIVED USING THE ANALOGY BETWEEN TERZAGHI'S EMPIRICAL CONSOLIDATION EQUATION AND A PHYSICAL MODEL. THIS WAS FOUND TO CORRELATE WELL WITH THE DEFORMATION CHARACTERISTICS OF THE SOIL. THE CLOSELY ASSOCIATED EFFECT OF ELECTROCHEMICAL HARDENING IS ALSO REPORTED, AND THE RELATIVE INFLUENCE OF PH VALUE IS DISCUSSED. IT WAS FOUND THAT A CONSOLIDATION ZONE, APPROXIMATELY A TENTH OF THE SAMPLE THICKNESS, WAS FORMED WITHIN THE SOIL AT A DISTANCE DEPENDING ON THE INITIAL PH. THE ELECTRODE MATERIAL GREATLY AFFECTED THE STRENGTH OF THIS CONSOLIDATED ZONE. /AUTHOR/
