ELECTRO-OSMOTIC CONSOLIDATION OF CLAY. A LABORATORY STUDY

KONSOLIDERING AV LERA MED ELKTROOSMOS

The purpose of this investigation is to make clear what factors affect the utilization of electro-osmosis for the consolidation of clays. Factors investigated are, inter alia, electrode distance, overburden pressure, free groundwater level, varying current and the resistivity of the clay. A number of tests are analyzed and the results can be used to determine the consolidation process and the final settlement. Changes in the geotechnical properties of the clay due to electro-osmosis are described as well as measures to avoid harmful effects. /TRRL/
