This paper is part of the copyrighted Journal of the Geotechnical Engineering Division; Proceedings of the American Society of Civil Engineers, Vol. 106, No. GT9, September, 1980. Manuscript was submitted for review for possible publication on October 25, 1979.The design of an excavation in rock requires an assessment of the likely response of the rock mass to a set of induced stresses. In order to predict this response, a knowledge is required of the complete stress-strain behavior and strength characteristics of the rock mass and of the influence of time on these properties.Introduction
