Laboratory Testing and Interpretation of Rock Properties

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).
