The paper describes the results of oedometer tests carried out with samples fromEemian fresh-water deposits and the methods used to determine the preconsolidation pressure from the test results. The influence of creep in the material onthe apparent preconsolidation pressure is estimated from a model set up by MoustJacobsen in 1992. The test results do not show any significant difference in thedetermined values of the overconsolidation ratio (OCR) for the samples fromHollerup and SolsØ, east and west of the main stationary line for the last ice sheetin Weichselian, respectively. The results, however, te11 nothing about the kind ofactions, which has caused the overconsolidation. The determined OCR-valuesmight be due to previous ice caps but a big difference in the two values from Solsoindicates a considerable influence from other actions. The sediments from Hollerupand SolsØ are not identical, and the effect of temperature, chemical and biologicalprocesses on the apparent preconsolidation pressure has not been evaluated.
