چکیده :
This paper presents the theoretical background of an elastic electro-osmosis consolidation model for saturated
soils experiencing large strains, which considers volumetric strains induced by changes in both
the hydraulic and electric driven pore water flows. Three fully coupled governing equations, considering
the soil mechanical behaviour, pore water transport and electrical field, and their numerical implementation
within an updated Lagrangian finite element formulation, are presented. The proposed model is
first verified against a classical one-dimensional analytical solution for electro-osmosis consolidation
to demonstrate its accuracy and efficiency. Then, various numerical examples are investigated to study
the deformation characteristics and time dependent evolution of excess pore pressure. Finally, the importance
of considering large strains in a consistent and proper way is demonstrated, and differences compared
to models based on small strain theory are highlighted.
