MEASUREMENT OF COHESION AND ANGLE OF INTERNAL FRICTION USING CUBICAL TRIAXIAL TESTER AND COMPARISON WITH COMPUTER CONTROLLED SHEAR CELL

摘要: ABSTRACT A flexible boundary-type cubical triaxial tester (CTT) was used to measure the flow parameters, i.e., cohesion and angle of internal friction, Mohr-Coulomb model. The three test materials in this study were BCR limestone, ground silica wheat flour. Flow parameters for these have been reported literature using different shear testers. comparison between CTT published computer controlled cell (CCSC) results showed that for: 1) limestone -- at low consolidation loads, comparable; however, there differences 12.5 kPa friction stress 6.6 kPa, 2) parameter values comparable 2.8 8.4 kPa, 3) flour — different, comparable. attributed differing initial bulk density lack kn...
