CHARACTERIZATION OF SEEPAGE AND DRYING ON LIGHT WEIGHT SOIL WITH AIR FOAM USING X-RAY CT METHOD

Abstract

The purpose of this paper is to characterize seepage and dying properties of light weight soils with air foams using industrial X-ray CT scanner. A series of water absorption test and drying test were conducted using in-situ light weight soils which were sampled at the trial construction site of new Kumamoto seaport, Japan. A series of CT scanning for those specimens during the tests were also conducted for along period and the effect of air foams for seepage and drying was evaluated. Finally, the effectiveness of industrial X-ray CT scanner in geotechnical engineering was confirmed based on those results.
