STATE-OF-THE-ART OF ONE DIMENSIONAL CONSOLIDATION

Terzaghi's classical one dimensional theory of consolidation appears to be the only consolidation theory in general use. However, both field and laboratory observations indicate that there are limitations in the theory due to the oversimplification of its assumptions. Various theories and rheological models have therefore been developed in order to explain these discrepancies and to better describe the whole consolidation process. Consideration is given to the establishment of the classical theory and its limitations, as well as the discrepancies between observed and predicted behaviour. Different theories and rheological models, both linear and non-linear, are reviewed. The limitations of these models and the possible causes of secondary consolidation are also discussed. Finally the various factors affecting the reliability of oedometer test results are examined. Part of the report is concerned with the development of, and advantages to be gained from numerous continuous loading consolidation tests. Some consideration is also given to large strain theory and the self-weight effect on soft soil consolidation. Finally, various methods for the determination of preconsolidation pressure and consolidation coefficient together with their applicabilities are described. (Author/TRRL)
