STRENGTH CRITERION OF ROCKS

To investigate the strength characteristics of soft rocks, consolidated-drained triaxial compression tests were performed with mudstones, siltstones, tuff, weathered granite and so on. Maximum stress of applied confining pressure was about 30 mpa. Radial compression tests under confining pressure were also performed to study the mechanical properties under tensile stresses. The applicability of proposed power function to the hard rocks and rock masses were investigated. Consequently, it is clarified that the proposed equation can be applied to the hard rocks which has the unconfined compressive strength of 20-200 mpa and also applied to the closely jointed rocks which can be regarded as the model of rock masses.
