An oedometer has been developed that may be used to study the rate of consolidation occurring at various depths within a soil specimen. Test results obtained with this oedometer show that a small quasi-preconsolidation pressure is induced in a normally consolidated soil, although a large resting period between load increments was not used. Tests on undisturbed soils further suggest that, for the small resting periods used, this quasi-preconsolidation pressure varies with the distance from what was the permeable boundary during the previous load increment test. Terzaghi's theory is extended to take account of a constant preconsolidation pressure whose magnitude is less than the final pressure. This theory is used to evaluate previously published results of laboratory tests where pore-water pressures have been measured, and also on published field record.
