Variability of permeability coefficient values of green clays from Bełchatów in one-dimensional consolidation testing
Sebastian KOWALCZYK

The article discusses the values of the permeability coefficient obtained in the consolidometric tests with continuous loading (CL) on samples of green clay from the Bełchatów lignite mine. A wide range of differences in the coefficient value was compared to the values of pore water pressure with regard to total stress (the pore water pressure parameter CCL). On the basis of the obtained test results we present the possibility of an effective determination of the permeability coefficient for low permeability soils in consolidation tests conducted in the conditions of continuous loading.

Keywords: consolidation, CL consolidation test, coefficient of permeability, pore water pressure parameter CCL
