Abstract
Summary
The results of a triaxial measurements on drained smectite rich shale have been analyzed. Static and dynamic properties of the shale were found to depend on shale matrix alteration due to differential thermal expansion and chemical alteration effects. Strong creep has been observed, which seems to originate from poroelastic effects, notably pore fluid drainage, and from rearrangement of matrix and pore space.
