Laboratory measurement of poroelastic and hydraulic constants of sedimentary rocks focused on pore water discharge from specimen with its deformation

摘要

The relation between rock mass deformation and groundwater behavior is of importance for several fields in earth science and engineering including geophysics, structural geology, rock physics, engineering geology, and geomechanics. The knowledge of this relation is needed particularly for repositories design for radioactive waste disposal. In terms of a geological barrier of the repository system, sedimentary formations are predominant to guarantee that the radioactivity cannot escape for several centuries.
