Özet

The modulus of elasticity of rock material (E(i)) is an important rock property that is used, as an input parameter in the design stage of engineering projects. such as dam and tunnel constructions, mining excavations, and so forth. However, determination of the modulus of elasticity is sometimes difficult to obtain by laboratory tests because high-quality cores are required. For this reason, empirical methods for-predicting the modulus of elasticity of rock material have been popular research topics in recently published literature. In this study, the relationships between the uniaxial compressive. strength (UCS), unit weight (gamma) and modulus of elasticity for different types of rocks were analysed by using 177 data obtained from laboratory tests carried out on cores obtained from drill holes within the area of the Kadikoy-Kartal Metro line (Istanbul, Turkey).
