抜粋

Mechanical properties of compacted bentonite proposed as one of buffer material for engineering barrier system in high-level radioactive waste disposal were studied by using the laboratory test results. The test results showed that the effective stress concept can be applied to the mechanical behavior of the compacted bentonite. In order to evaluate the applicability of two constitutive models, Sekiguchi-Ohta model and Adachi-Oka model, to the compacted betonite, the models were compared with the test results. Good agreements between the models and the test results were obtained from this comparison.
