Abstract:	The degradation in dilation and post-peak strength along irregularities is modeled using the plastic work done in shear. A dimensionless product of plastic work, rock strength, and wavelength of irregularities has been developed which fits the direct shear test results. An approach to scaling shear strength and shear displacement from laboratory to in the field is suggested. Analyses are correlated with shear displacements on the roadway and inclinometer readings measured in the rock ridge.
