The Distinct element analysis for swelling pressure test of bentonite; Discussion on the effects of wall friction force and aspect ratio of specimen

Shimizu, Hiroyuki*; Kikuchi, Hirohito; Tanai, Kenji ; Fujita, Tomoo

For geological isolation systems for HLW, due to the lack of standardization of swelling test method for bentonite as a buffer material, the accuracy and reproducibility of the results are not sufficiently proved. In this study, bentonite swelling pressure test were simulated by newly developed distinct element method, and the effects of wall friction force and aspect ratio of bentonite specimen were discussed.
