Abstract

The research focused on investigating key aspects of soil and tailings behavior in a torsional shear hollow cylinder apparatus, as listed below:

1. The instability of sands under the constant shear drained stress-path with focus on below slope stress conditions.

2. A comparison of the strength of loose tailings measured in a direct simple shear apparatus and in the hollow cylinder shearing under simple shear conditions.

3. The development of a procedure to undertake plane strain, drained simple shear testing in the TSHC.

4. The drained and undrained behavior of tailings under general multiaxial conditions.
