It is pointed out that while the above paper reports a thorough study of the fundamental mechanism, the study also has the basic data to consider K sub 0 (t) during the process of consolidation under a particular loading increment. Supplementing selective data on the time-dependent behavior of K sub 0 (coefficient of earth pressure at rest) will provide invaluable information in establishing the appropriate rheological behavior of the particular clay sample-formation under study. A viscoelastic model has been considered as a first approximation to establish the time-dependent nature of K sub 0 clay formation during the geological time span. K sub o (t) is about unity at the initial stage of slurry depesition. Afterwards, K sub 0 (t) exhibits a low minimum value with the formation of soil skeleton during the initial stage of primary consolidation, and then reincreases and approaches equilibrium value in line with the stage of secondary consolidation.
