A comment on the similarity of the coupled consolidation models with point-symmetry

The system of partial differential equations known from the theory of the oedometric tests and from the dissipation tests are summarized into a single model in the function of the space dimension and basic part of the analytical solution is presented. The general solution is treated for the special case of two sets of boundary conditions, resulting in two model-families. It is found that the well-known K-0 compression state (dimension 1) or the cavity expansion states (dimensions 2 and 3) constitute a part of the general solution. Within a model-family, the precise (1 dimensional case) and the approximate (2 and 3 dimensional cases) roots of the '' boundary condition equations '' are '' identical '' allowing the introduction of a time factor.
