高レベル放射性廃棄物地層処分場で仕様可能なグラウト浸透モデルとして、室内試験結果にGustafson and Stillモデルを適用し、その有効性を確認した。

This study aims at validating applicability of the theoretical formula by Gustafson and Still to analysis of permeation behavior of Bingham fluid into a one-dimensional micro-fissure by comparing analysis results with laboratory tests data conducted using bentonite slurry as a Bingham fluid. The results showed that the calculation values by Gustafson and Stille model agreed well with values of laboratory penetration test.
