A general condition for the strength standard of regular jointed rocks is obtained in this article. The procedure is depend on the performance of the homogenization procedure of periodic media within the framework of the yield plan principles. A rigorous explicit statement of the macroscopic standard is given as a sunordinate of the strongest features of the virgin rock and of the joints shaped as ports. Consideration is concentrated on the special case of an endlessly persistence entire rock. It is displayed in specific how the related velocity jumps for the homogenized medium can be determined from the presentation of the set of permissible stress vectors acting upon an elementary surface. This contains issues such as the significations of the intermittent nature of rock masses, extent states and failure modalities, strength standard, characteristic quantities and partial components for rock mass components, rock mass features, use of classification systems in plan, among the most significant issues. Anisotropy in the physical and mechanical behavior of the rocks is an effective parameter in determination of their engineering characteristics. The sedimentary and metamorphic rocks show anisotropic behavior due to higher lamination, bedding and flakiness. In this paper, the anisotropic behavior of clay rocks such as shale has been investigated. These types of rocks arise a lot of problems for engineers in designing the associated structures. The most important characteristic of this type of rocks is that they are composed of ultra-fine clay and silt particles. The discontinuities, fissures, and bedding layers and lamination in the shale masses change the mechanical characteristics and anisotropic behavior of these rock masses against the applied forces. Here, the anisotropic behavior of these types of rocks and the effect of different parameters and changes due to anisotropy are discussed.
