本業務では,岐阜県瑞浪市で実施されている「超深地層研究計画」の中での,地表からの調査予測研究段階の一環として,深度500m近傍までの物性値を概略的に把握することを目的として,MIZ-1号孔の岩芯を用いた室内物理・力学物性試験を行い,瑞浪層群,土岐花崗岩の物理特性,力学特性の基礎的な知見を得た。

The research is carry out as part of Phase I (Surface-based Investigation Phase) in MIU (Mizunami Underground Research Laboratory) Project located on the MIU construction site in Mizunami City, Gihu Prefecture. The purpose of this research is to investigate the Physical property of rock in depyh from surface to the of 500m. Physical and mechanical properties of Mizunami Group and Toki granite have been obtained in our laboratory by using the core obtained from MIZ-1 bore hole.
