METHODS TO QUANTIFY THE PARAMETERS APPLIED IN THE …

The uniaxial compressive strength of the rock constitutes the highest strength limit of the actual rock mass. ISRM (1981) has defined the uniaxial strength of a rock to samples of 50 mm diameter. A rock is, however, a fabric of minerals and grains bound or welded together. The rock therefore includes microscopic cracks and fissures.
