<dc:description>The main scope of this paper is to present an alternative to tackle the problem of the non symmetries arising in the&#13;
solution of the nonlinear couple consolidation problem based on a combination of different stress states. Being originally a non&#13;
symmetric problem, it may be straightforward reduced to a symmetric one, and the conditions in which this reduction may be&#13;
carried out, are addressed. Non linear saturation-suction and permeability-suction functions were regarded. The geometric&#13;
model was developed considering an updated lagrangian description with a co-rotated Kirchhoff stress tensor. This description&#13;
leads to a non-symmetric stiffness matrix and a simple alternative, using a symmetric constitutive matrix, is addressed to&#13;
overcome this situation. The whole equation system was solved using an open finite element code FECCUND, developed by&#13;
the authors. In order to validate the model, various examples, for which previous solutions are known, were solved. The use of&#13;
either a strongly non linear and no symmetric formulation or a simple symmetric formulation with accurate prediction in&#13;
deformation and pore-pressures is extremely dependent on the soil characteristic curves and on the shear efforts level, as well.&#13;
A numerical example show the predictive capability of this geometrically non linear fully coupled model for attaining the&#13;
proposed goal.</dc:description>
