In the present work one-dimensional consolidation is treated as a phenomenon of diffusion and the governing physical equation is derived using probabilistic considerations. The similarity between diffusion of solids in a field of water and that of a substance dispersed in a liquid is exploited to determine the analytical expression of the coefficient of diffusion. Differences between laboratory and field conditions are considered for the prediction of the expected rates of dissipation of pore-water pressure. Finally, a simple scaling procedure is presented, of time to space increments, to provide recurrence formulas.
