A NEW CURVE FITTING METHOD FOR THE TRIAXIAL STRENGTH OF ROCKS. LARGE ROCK CAVERNS - PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM, HELSINKI, FINLAND, 25-28 AUGUST 1986. VOLUME 2

A new empirical criterion is proposed to describe the triaxial strength of rocks. According to this criterion, the Mohr failure envelopes of rocks are described by cycloidal curves. Application to published and laboratory determined triaxial test results shows that the criterion gives an upperbound curve fit to the triaxial strength Mohr failure circles of rocks. The method is easy and practical to use and is recommended for application to the design of underground openings. For the covering abstract of the symposium see IRRD 810647. (Author/TRRL)
