Description: In some situations (e.g. non-monotonic initial pore water pressure distribution), an inflexion point does not appear in the total stress time curve of the dilatometer dissipation test. In the suggested evaluation method the total stress and some derived pore water pressures are evaluated separately as a function of two parameters and the solutions are matched. The problem of dilatometer dissipation test evaluation without the inflexion point information becomes solvable at the expense of greater numerical work. Some reliability criteria can be given on the basis of the pore water pressure data evaluation.
