Persian Title: Using the Point Load Test to Determine the Uniaxial Compressive Strength of marble and travertine rocks
Persian Abstract: - Abstract Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used. These factors have been proposed by various researchers and are dependent upon rock type. This study involved the uniaxial compressive testing and point load testing of marble and travertine rocks from ten different rock quarries in Iran. Around 300 individual test results, including 159 uniaxial strength tests and 139 point load tests, were used in this study. Rock lithologies were classified into two general categories and conversion factors were determined for these categories. This allows for intact rock strength data to be made available through point load testing for numerical geotechnical analysis and empirical rock mass classification systems such as the Rock Mass Rating (RMR).
