| Research Abstract |
It is known that the deformation and flow properties of a rock mass are governed by the discontinuities involved in the rock mass. When a tunnel is excavated, the stress around the tunnel changes complicatedly. However, the changes of the deformation and flow properties under the complicated stress remain poorly understood. Thus, in this study, the flow-deformation coupling experiments are conducted, and the effects of the existence or non-existence of discontinuity, the opening of discontinuityand the stress change on the deformation and flow properties are examined. In consequence, it is clarified that the flow property of the discontinuous rock mass changes rapidly in loading or unloading to a specimen with a discontinuity.
