Residual strength of granitic rocks

When carrying out compressive tests on rock specimens, a stress plateau is typically attained following peak strength within strain range few times larger than the at strength. This level commonly known as residual A large database of these granitic specimens has been compiled and analyzed in detail with aim improving understanding this type rock. It observed that physical scale does not significantly change threshold also shown to be independent initial jointing volume. The implication findings derived from specimen testing can potentially extended mass scale, least for rocks. Three one-parameter models have used fit laboratory test data rocks, all them are reasonably approximate actual data. Additionally, parameters varied studied rocks varying pre-jointing tend very different, covering limited values. Ultimately, potential errors simple excavation analysis might result priori assumptions regarding masses quantified.
