Classification of rocks for rock mechanics: M38-8/16E-PDF

"In the field of rock mechanics efficient communication between the laboratory and the field engineers, operators and contractors is important. For example, a rock may be described as a Cretaceous shale with quartz and pyrite, etc. However, some of the principal factors of practical interest would be: (a) is it jointed, badly fractured, distinctly layered or massive; (b) does it fail in a brittle or plastic manner; (c) is it viscous before failure; (d) can the information be interpolated between boreholes, etc.? Hence it is important that the significant properties of both the substance and the mass be recognized and the appropriate information obtained so that an initial appraisal can be made of any potential problems. Classification can be on the basis of natural, inherent characteristics or on the basis of purpose. The classification of rocks for rock mechanics problems should be functional, and the words used for communication between groups should be defined, widely recognised and related to the use of the information"--Introd., p. 421.
