| Outline of Final Research Achievements |
When deep seated sedimentary rocks are excavated for radioactive waste disposal, the new environment may cause change in water content in surrounding rock of tunnel wall. Rock, which is one of the porous media, should deform in response to the change. In fact, it is not clear how much rock deform and how rock deform. In this study, coupled behavior between deformation and moisture distribution process is investigated by laboratory experiments and in situ measurements. As a result, it is elucidated that moisture transfer occurs dynamically between the air and pores in rock.
