CONSOLIDATION OF DEEP DEPOSITS OF HOMOGENEOUS CLAY

Under embankments and earth dams the load ratio will generally be greater than two (the standard oedometer ratio) to a depth of twice the embankment height. In deep deposits large variations in compressibility and permeability will occur throughout the depth of the deposit. In order to help account for these variations a theory and solutions are presented to cover a large number of practical problems involving one-dimensional drainage for a homogeneous soil which obeys the relationship The theory presented often predicts large differences from rates of consolidation which might have been predicted from the assumptions of the standard linear theory. An approximate method of applying the theory to the consolidation of soils by drain wells is presented. Two case records are referred to which show variation from the linear theory predictions which could be accounted for by the theory presented. © 1969, Thomas Telford Ltd. All rights reserved.
