Outline of Final Research Achievements

In order to use underground environment as an engineering space (e.g. geological isolation of high-level nuclear waste), understanding of the mechanical properties of the rock material is essential. Strain measurements of rock material under uniaxial compression using neutron diffraction technique were performed, and the mechanism of strain accumulation in rock material was analyzed. In addition, triaxial compression apparatus for neutron experiments was desighned and developed.
Commissioning and feasibility tests of the newly designed triaxial compression apparatus was performed, and strain measurements of rock materials using neutron diffraction under triaxial compression were also carried out. The strain accumulation mechanism is under analysis.

Academic Significance and Societal Importance of the Research Achievements

地下環境の複雑な応力状態における岩石材料の力学的特性を理解するために、中性子実験用封圧三軸圧縮装置を開発した。岩石材料の封圧三軸圧縮試験をしながら中性子回折法を用いたひずみ測定を行うのは世界で初めての試みである。本実験システムを用いる事により、封圧三軸圧縮下における岩石材料の新たなひずみに関する知見が得られるようになると考えられる。
