A Theory of Consolidation of Soft Sediments.
Abstract
The objective of the research undertaken was to provide a theory of consolidation of fine-grained soils of sufficient generality to enable predictions to be made in engineering situations where the sediment is so soft that allowance must be made for changes in material properties during the progress of consolidation, where large strains and displacements must occur, account being taken of pore water flow in two or three dimensions. The study proceeded in two Stages. The first Stage involved a critical examination of presently available theories of consolidation which were modified and extended to meet the objective of the research. The aim in Stage I was to develop mathematical equations governing the consolidation process based on physical assumptions which accord with the known behavior of soft sediments. In Stage II, numerical procedures and associated algorithms were considered based on the analysis which would permit prediction of the distribution and time variation within the medium of quantities of engineering interest, namely: the pore water pressure, the effective stresses and the void ratio.
