- Аннотация: The paper discusses the elastic properties of rock specimens studied by static and dynamic methods; the static and dynamic elastic moduli are comparatively analyzed. We examined two sets of differently fractured specimens of Voronezh granite sampled at different depths (up to 400 m). Two sets of ten specimens each were selected on the basis of total core recovery, solid core recovery, and rock quality designation. The static modulus of elasticity was determined from stress and deformation measurements made with a TP-1—1500 press and a tensometric complex (with integrated software), respectively. The dynamic modulus of elasticity was determined from the measured elastic wave velocities and densities of the specimens. Correlation and regression analysis was performed to determine the relationship between the static and dynamic modulus of elasticity for two sets of specimens. As far as the set of fractured granite specimens is concerned, it is found that less fractured granite specimens are characterized by more strong correlation between the elastic moduli, other specimens show a moderate correlation. It is also found that the relationship between the dynamic and static moduli has a linear character for the whole series of specimens; on average, the dynamic modulus of elasticity is 2.11 times larger than the static one, which does not differ significantly from two separate sets.
