Empirical correlation of uniaxial compressive strength and primary wave velocity of Malaysian granites

Uniaxial compressive strength (UCS) plays a significant role in influencing the
stability of structures such as cut slopes and excavation in rock masses. The rock material
parameter of UCS also serves as an input parameter for geomechanical modeling in fracture
basement studies. However, uniaxial compressive strength test (UCT), requires sample
preparation, together with expensive and destructive laboratory testing and thus the limited
rock samples has becomes a disadvantage.
