A time dependent model for lining pressure based on strength concepts
Abstract
Weak rocks when subjected to moderately high confining and deviatoric stresses tend to exhibit time dependent deformation. This is most commonly characterised through phenomenological models of time-hardening strain under constant stress. An alternative description based on strength reduction with time is suggested. The implications of this approach for the design of shaft linings in evaporite rocks are discussed.
