Study on Influence of Joint Orientation on Rock Engineering Properties for Mining and Infrastructure Design

Abstract

Abstract Rock strength is the most important parameter for mining and infrastructure design. Accurate determination of rock strength is needed as a basis for implementing safe and economical rock engineering projects such as tunnels, open pit mines, and slope cutting for roadways. Rock is heterogeneous, anisotropic, and discontinuous materials. The discontinuities can be found as joints, faults, fissures, bedding, etc. In rock mechanics, the term of joint is generally used to represent all types of discontinuities. Joints are the planes of weakness in rock masses and can be found in various geometrical shapes, depending on past geological processes. This research briefly focuses to study the influence of joint orientation on rock strength based on UCS test. Application of this research could be recommend applying for mining and infrastructure design.
