Web7 Apr 2024 · Rock mass: The large volume of rock intersected by discontinuities is known as rock mass. The rock mass is heterogeneous in nature due to variation in rock type, discontinuities and degree of weathering. Rock mass = Intact rock + Discontinuities The discontinuities highly influence the overall strength of rock mass. Webmechanical behavior of rock masses. In most rock masses the discontinuities form planes of weakness or surfaces of separation, including foliation and bedding joints, joints, fractures, and zones of crushing or shearing. These discontinuities usually control the strength, deformation, and permeability of rock masses. Most engineering
