Rock
Triaxial Compressive Strength, Young's Modulus, Poisson's ratio
A rock core sample is cut to length and the ends are machined flat. The specimen is placed in a triaxial loading chamber subjected to confining pressure and, if required, heated to the desired test temperature. Axial load is continuously increased on the specimen, and deformation is monitored as a function of load. Deformation and strength of rock are known to be functions of confining pressure. The triaxial compression test is commonly used to simulate the stress conditions under which most underground rock masses exist.
