Strength Criterion of Rocks

Soils and Foundations, 1980
ABSTRACT 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.
