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. Rather large samples are required to
