Individual joints

Research scope

The characterization and representation of individual fractures (joints) – an essential component of jointed rock mass characterization and representation – range from geometrical to mechanical and hydraulic aspects. Hence, the geometry (“roughness”), the shear behavior regarding both deformability and resistance, and the hydraulic behavior of individual fractures have been studied. Specific research topics on individual fractures have covered experiments and models of surface geometry and aperture, experiments and models of shearing behavior, and – most recently – flow investigation, which combines geometric, mechanical and hydraulic aspects.
