1. Introduction. In geotechnical engineering, there are several types of discontinuities associated with shear zones, bedding planes and faults that can affect the strength and stiffness of rock mass (Shen, 1995; Eberhardt et al., 1998).Some studies were conducted to analyze the process of initiation, propagation and coalescence of pre-existing cracks in rocks or rock-like materials (e.g ...

Size corrections are applied to obtain the point load strength index, Is(50), of a rock specimen. A strength anisotropy index, Ia(50), is determined when Is(50) values are measured perpendicular and parallel to planes of weakness. Commentary The test can be performed in the field with portable equipment or in the laboratory (Figure 8-1).
