"This supplement describes tests to determine strength and elastic properties of rock substance and of discontinuities in rock. Elastic modulus and Poisson's ratio are determined from stress-strain measurements during uniaxial compression.The ultrasonic elastic constants are determined from measurements of sound velocity. Triaxial compressive strength is determined by loading a cylindrical sample axially and laterally. Residual angle of friction of rock specimens is determined from shear strength measurements along a sawcut plane. Discontinuity shear strengths are determined by the direct shear test, and by triaxial testing. Strength properties of crushed rock are determined by triaxial testing. Time dependent deformation and strength properties of rock specimens are determined by long-term uniaxial compressive tests"--Abstract. Slopes (Soil mechanics) Strip mining Gyenge, M.
