Abstract

The article deals with the interpretation of consolidation test in order to determine the preconsolidation stress; this is done by reviewing different methods. A main point in the article is the interaction between the consolidation and the secondary consolidation strains, and the methods used to separate the two strain types. This is in Denmark traditionally done by a √(t)-log(t) description, where the secondary consolidation first starts when the consolidation process is over. This assumption gives an uncertain description of the strain process, since the two processes in reality run simultaneously. By use of the ANACONDA-method the two processes are assumed to run simultaneously. The method gives a more accurate description of the strain process, and thereby a better determination of the deformation properties. The methods for determining clay properties are demonstrated on Søvind Marl and the difference in results are shown.
