Compressibility of Organic Soils Polluted with Diesel Oil

The paper presents results of experimental study on the compressibility of soils contaminated by diesel oil from Żuławy region. The investigation results show that compressibility of the soils increases with increasing diesel oil content. A significant increasing in compression was found when diesel oil content in soil exceeded 3%. The compression index Cc changes inversely to changes in the dielectrical constant of a porous medium. The index Cc for contaminated organic soil can be estimated from the established compression index of "clean" soil and dielectric constant of the porous medium of polluted soil
