Research Abstract

Variation of the coefficient of permeability with the strength recovery phenomenon was researched experimentally. When investigating the long-term behavior of the underground structures, strength recovery and decrease of the coefficient of permeability are very important. The coefficients of permeability for the original rock specimen, fractured specimen in the progress of strength recovery, and the compacted specimen after the compaction test were investigated experimentally. The coefficient of permeability became small moderately with the increase of the axial load applied in the compaction test. Experimental results from this study showed that the decrease of the coefficient of permeability progressed with strength recovery, which is the preferable trend for the repositories in rock mass.
