摘要

Generally anisotropy is one of the factors that effect the behaviour of rocks. The properties of such rocks vary with direction. In general, rocks have some degrees of anisotropy and isotropic rocks are rarely found in nature (Kwasniewski, 1993). The rock anisotropy is mainly due to the presence of foliation, cleavage, schistosity, joints, micro and macro fissures and bedding plane (Al-Harti, 1998). Igneous rocks are more isotropic in nature than sedimentary and metamorphic rocks (Ramamurthy, 1993, 1993), whereas metamorphic rocks are mostly anisotropic. Rocks such as slates, shales, phyllites and gneisses have anisotropic behaviour.
