Question
- Can TRIAXIAL TESTS be performed on sand samples? Briefly explain.
- The results of an undrained triaxial test on a clay soil sample are given in table below
| Cell Pressure (kN/m2) | 200 | 400 | 600 |
| Additional Axial Load at Failure (N) | 342 | 388 |
465 |
Each sample, originally 76mm long and 38mm in diameter, experienced a vertical deformation of 5.1mm.
- Evaluate the stress at failure for each cell pressure given in table above.
- Draw Mohr Circles and determine the shear strength parameters of the soil.
