Abstract : The study investigates the validity of the power law for expressing the viscous resistance to compression observed in clays and shows that it can be satisfactorily used for this purpose. However, it is suggested that the three-parameter Ellis model might better describe viscous resistance to compression. It is also shown that the constants appearing in the power law can be related by means of simple equations to the effective normal pressure and to the chemical composition of the clay mineral. Consolidation studies on pelagic sediments indicate that these are highly compressible and normally consolidated. Structures founded on these sediments will be subject to large settlements. (Author)
