| Rock core samples of mainly limestone were obtained from the Getchell Mine, located near Winnemucca, Nevada. Tests of direct shear, sonic velocity, uniaxial compression, and Brazilian tension have been performed at the rock mechanics lab, University of Nevada, Reno.;The evaluations of ASTM (American Society for Testing and Materials) Standards and ISRM (International Society for Rock Mechanics) recommended procedures regarding the tests have raised questions about (1) the method by ASTM for checking specimen end flatness and (2) specimen density calculation for sonic velocity test. The method needs to be modified or needs at least clearer description.;A theoretical propagated error analysis has derived the equations for conducting error estimations for these tests. The error results of sonic velocity tests appear practical.;Least-squares linear regression was applied for establishing the relationship between rock properties. A very good linear relation existed between the P-wave and S-wave velocities. |
