Abstract

According to the present radioactive waste geological disposal concept, a disposal facility is constituted from the bentonite engineered barrier, cementitious engineered barrier and natural barriers. In order to obtain the validity of the geological disposal concept, the high impermeability of bentonite-engineered barrier is necessary. Therefore, many various laboratory tests were implemented. There are, however, few researches which summarized these test results integratively in the viewpoint of soil mechanics. In this paper, both interpretations of extraordinary swelling and compression behaviors of the compacted bentonite were discussed based on the soil mechanics using constant water-content line and constant degree-of-saturation line in the e-lnσν' plane.
