Özet

Mechanical rock excavation projects require uniaxial compressive strength (UCS) and static modulus of elasticity (E) of the intact rock material. High-quality core specimens of proper geometry are needed for the direct determination of these parameters. However, it is not always possible to obtain suitable specimens from highly fractured and/or weathered rocks for this purpose. Therefore, models predicting UCS and E based on rock index tests and intact rock properties have become alternative methods.
