Resumo

ALTINDAG, R. Correlation between P-wave velocity and some mechanical properties for sedimentary rocks. J. S. Afr. Inst. Min. Metall. [online]. 2012, vol.112, n.3, pp. 229-237. ISSN 2411-9717.

Engineers and researchers need to estimate the mechanical properties of rocks from P-wave velocity. In previous studies, the researchers have investigated either the limited values or all the data belonging to sedimentary, igneous, and metamorphic rocks together in the same statistical analysis. In this study, the raw data pertaining to only sedimentary rocks was taken from previous studies and evaluated. For this purpose, a total of 97 samples of sedimentary rock types were subjected to statistical analysis. First, the relationships between P-wave velocity and physical-mechanical properties were investigated by simple regression analysis. All the data were then subjected to multi-regression analysis. Some empirical equations with high correlation coefficients were derived for rock engineers. The equations obtained from the analyses are compared with previous equations found in literature.

Palavras-chave : P-wave velocity; mechanical properties; sedimentary rocks; mechanical properties; brittleness.
