This article focuses on the uniaxial compressive strength (UCS) of homogeneous and heterogeneous rocks. Critical factors impacting the UCS of rocks are reviewed and then separate assessments of UCS data from homogeneous and heterogeneous rocks are presented. The variability (coefficient of variation) of UCS test results for homogeneous rocks is found to be generally 35%. Failure mode variation is found to be the cause of the variability of UCS test results in heterogeneous rocks. Empirical… CONTINUE READING
