Triaxial vs direct shear test
Web1 day ago · Li et al. determined from the triaxial shear test that the creep characteristics of frozen hydrate, and the host material of the sample is kaolin clay. In the study, the relationship between axial strain, strain rate and deviator stress, confining pressure, inside temperature of the sample is clarified [33]. WebDave Anderson demonstrates how a consolidated undrained (CU) triaxial test is performed on sand.

WebColloidal silica can quickly seep through sand and then form silica gels to cement sand particles. To improve the strength of sand seeped by colloidal silica, carbon nanotubes were dispersed in the colloidal silica to form carbon-nanotube-reinforced sand-gel composites. Then triaxial tests were performed to explore how carbon nanotube content affects shear … WebThe direct shear test determines the consolidated, drained strength properties of a sample. ... as requiring more advance tests in comparison to E0 and E50 parameters that may be evaluated on the basis of standard triaxial tests with shear wave velocity measurement.
