STRENGTHENING OF ROCK AGAINST SHOCK EFFECTS. TESTS FOR STRENGTH CHARACTERISTICS OF ROCK PILEDRIVER PROJECT

Abstract

This report presents results of tests for shear, compressive, and tensile strength characteristics of rock of the type which will be encountered and subject to rock strengthening techniques and evaluation as part of Piledriver Project. Triaxial compression tests were made of intact rock and of rock having natural healed or open joints, and joints smoothly sawed in the laboratory. Unconfined compression and direct tension tests were made of intact rock and of rock containing natural healed joints. Certain testing and instrumentation techniques were developed and are described in detail where it is considered the information may be of value in future work of a similar nature. (Author)
