In-Situ Rock Stress Measurement in the Active Fault Survey Tunnel

Takebe, Akimitsu*; Higashihara, Masami*; Takami, Akira*

The comprehensive studies are being carried out for the deep structure of the active fault, characteristics of the fault fracture zone and stress states of the rock nearby the fault. As one of them, an in-situ rock stress measurement by hydrofracturing method was attempted on a nearby active fault in the survey tunnel at Kamioka Mine. This report describes the hydrofracturing method and results of the in-situ rock stress measurement.
