Title: Consolidation Characteristics of Selected North Pacific Sediment Clays: ABSTRACT

Author(s): John P. Nielsen, R. J. Smith

Article Type: Meeting abstract

Abstract:

A recent theoretical analogy of the consolidation process of clay-type sediments, with reference to their viscous resistance to compression, indicates that engineering properties other than rheology can be determined from the consolidation test. A consideration of the lithology of selected north Pacific sediment cores, correlated with consolidation and other soil-mechanics test results, verifies this conclusion. In this circumstance the pore fluid functions as a highly viscous media which controls the deformation of such sediments under load. A mathematical statement of this viscous resistance to compression is combined with a new stress equation to present a statement which adequately expresses the consolidation process. Interpretation of consolidation curves using this pproach enables prediction of viscous resistance to shear. This resistance is controlled primarily by stress level and to a lesser degree by compositional factors. These studies are supported by the conclusions of other researchers of the mechanical behavior of such materials.
