Deformation Modulus of Rock Masses: An Assessment of the Existing Empirical Equations

Rock mass deformation modulus is an important parameter for all geotechnical applications. However, the determination of rock mass deformation modulus with in situ tests are highly expensive and time consuming. For this reason, rock engineers and engineering geologists have proposed numerous empirical equations based on various rock mass and intact rock properties to estimate the deformation modulus of rock masses. In the present study, an...
