CONSOLIDATION OF RANDOMLY HETEROGENEOUS CLAY STRATA

A simulation procedure is used to analyze the influence of a randomly varying coefficient of permeability on the one-dimensional consilidation settlement of clay layers. The method of analysis involves (a) simulating of soil profile when the basic characteristics of the homogeneous random function describing the soil permeability are known, (b) making the governing field equation discrete by means of an implicit finite difference scheme, and (c) statistically analyzing the resulting sample population when the simulation has been performed a sufficient number of times. When compared with results determined by the classical deterministic approach, the application of this analysis to a specific case shows significant differences and allows the use of standard procedures in significance testing, rather than the single estimate provided by the deterministic case, to make decisions at a given significance level.
