Determination of Stress in Rock—A a State-of-the-Art Report

Various procedures and associated instrumentation that have been used to measure the absolute or change in strain, deformation, and stress in rock are reviewed. The merits, limitations, and undesirable features in each procedure are discussed. The results of a number of in situ investigations in various rock types are presented, together with an appraisal of the state of stress that generally exists around underground openings in various types of rock. The report is concluded with recommendations for specifying the performance and characteristics of this class of equipment.
