Research Abstract |
Triaxial compression tests were carried out on Shikotsu welded tuff,Kimachi sandstone and Inada granite under several confining pressures and temperatures,aiming to clarify permeability variation and mechanisms of it. It was clarified thatpermeability decreased by failure for tuff and sandstone and that flow rate increased underhigh temperature. It would be expected that these findings will contribute for design andconstruction of safer underground openings with lower cost.
