Theory of Consolidation of Soft Sediments. I,
Abstract
The objectives of the research undertaken are 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 is proceeding in two Stages. The first Stage involves a critical examination of presently available theories of consolidation which are modified and extended to meet the objectives of the research. The aim in Stage I is to develop mathematical equations governing the consolidation process based on physical assumptions which accord with the known behaviour of soft sediments. In Stage II numerical procedures and associated algorithms will be 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. This may not be straightforward and analytical modifications to the Stage I equations may be needed to secure computable results which can be generated economically and efficiently. This first Interim Report is devoted to a synoptic account of the progress achieved in Stage I.
