An analytical solution of incompressible charged porous media

Abstract

A one-dimensional analytical solution is derived for free swelling and consolidation of a saturated charged porous medium. The derived equations describe infinitesimal deformation of charged porous media saturated with a fluid with dissolved cations and anions. In the one-dimensional case the governing equations reduce to a coupled diffusion equations for electrochemical potentials. Suitable initial and boundary conditions based on consolidation or free swelling experiments complete the equations. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
