Triaxial compressive test

Three different types of triaxial compression test are described. The tests are intended to measure strength of
cylindrical rock specimens as a function of confining pressure. The three test types differ from each other in
the manner by which the strength envelope is produced (Figs la-c). With test type I (“individual test”), individual points on the failure (peak strength)‘* envelope are obtained from several tests (Fig. la)2, while with test…
