This paper is based on work done by the authors in a study of the structural features at a quarry excavated in Chazy limestone on the Island of Montreal. Observations on failures on the quarry walls and benches were recorded, and back-analyses of small-scale failures were carried out, thus enabling an assessment to be made of the in-situ strength properties of the rock. Using this information, and data from shear tests in the laboratory, the authors made an analysis of the stability of the south wall of the quarry.
