Abstract
This paper presents an analytical procedure for hindcasting the genesis of a soft marine sediment which is consolidating under its own weight. The procedure is based upon the use of non-linear finite strain consolidation. This theory is reviewed. A formulation is developed which permits the computation of the progress of consolidation during the accumulation of a sediment column. A numerical procedure for solving the governing equation by the method of lines is outlined. The procedure is applied to the development of the geotechnical stratigraphy of Mississippi delta sediments. It is shown that an accurate calculation can be made of the present state of effective stresses and pore-water pressures. It is further shown that an accurate assessment of the present void ratio profile can be obtained.
