Prediction of uniaxial and triaxial strength of rocks from other measured physical properties

An attempt is made to correlate uniaxial and triaxial strength of Berea Sandstone and Indiana Limestone with the physical rock properties density, p-wave velocity, Poisson's Ratio, and Young's Modulus. Young's Modulus is the variable that correlates well most frequently with compressive strength. Both p-wave velocity and Poisson's Ratio correlate well with compressive strenth under certain conditions. Density is the poorest single indicator of strength. The results suggest that the best approach to the problem of strength prediction may be a multivariant curve fitting approach.Earth and Atmospheric Sciences, Department o
