摘要: L'electro-osmose, qui consiste a deplacer les constituants de la phase liquide dans un milieu poreux par l'application d'un champ electrique, intervient nombreux domaines : geotechnique, depollution des sols, biotechnologies... La partie I ce memoire propose une modelisation l'electro-osmose en deformable. Elle conduit l'ecriture dissipations et fait apparaitre contribution phenomenes transfert mecanique production d'entropie. II est consacree d'une relation generale electrolyte. Un banc experimental d'electro-osmose ete realise pour examiner couplages entre hydraulique electrique. Le materiau d'etude le gel d'Agar, diphasique souvent utilise comme modele tissus biologiques. III concerne prise compte deformation du squelette solide son couplage avec electro-osmotique. Certains aspects sont valides essais consolidation oedometrique d'Agar soumis sollicitations
