Abstract
Uniaxial compressive strength (UCS) and the Brazilian tensile strength (BTS) are the most commonly used rock properties. The UCS/BTS ratio is used as an indicator of rock brittleness and to estimate UCS from BTS (or vice versa). However, the relation between UCS and BTS has not been investigated in detail. This paper focuses on UCS/BTS ratio using the raw data pertaining to 1842 rock types from different research institutes. Regression analysis indicated that power law or exponential relations offers a better best fit correlation between UCS and BTS for each data set from different institute than linear function which has been typically offered in the past. Power function was also found to offer a better relationship between UCS and BTS for the all data under evaluation. The correlation coefficient of power function (r = 0.79) was higher than that of the linear function (r = 0.64).
