Time Effects on the Stress/Strain Properties of Clay Consolidated in the Laboratory.
Abstract
Samples of natural, undisturbed as well as artificially produced clays were consolidated under a pressure corresponding to the double consolidation pressure and were then left to rest under a reduced pressure and drained conditions. After various periods of rest, the samples were sheared under undrained conditions and it was observed that the strain at failure decreased and that the shear modulus increased with the time lapsed. This can be explained in terms of a shift of the energy spectrum to higher barrier values, the most probable physical equivalent being an improved number and strength of re-formed particle bonds, primarily of the clay/water-complex type.
