Suggested Methods for Determining the Strength of Rock Materials in Triaxial Compression, revised version


This test is intended to measure the strength of cylindri-cal rock specimens subjected to triaxial compression. This provides the values necessary to determine the strength envelope and from this the value of the inter-nal friction angle @ and the “apparent” cohesion C may be calculated.
