Triaxial Test
1. In a standard triaxial compression test, the intermediate principal stress (σ2) is equal to:
2. The deviator stress (σd) in a triaxial test is defined as:
3. When drainage is allowed during the consolidation stage but not during the shearing stage, the test is called a:
4. Which component of the triaxial apparatus is used to apply the confining pressure?
5. Skempton's pore pressure parameter 'B' for a fully saturated soil is theoretically equal to:
6. The main advantage of the triaxial test over the direct shear test is:
7. If the confining pressure (σ3) is 100 kPa and the axial stress at failure (σ1) is 300 kPa, the radius of the Mohr circle at failure is:
8. In an unconsolidated undrained (UU) test on a saturated clay, the failure envelope is:
9. During a triaxial test, the cross-sectional area of the specimen changes. The corrected area (Ac) is calculated from the initial area (A0) and axial strain (ε) as:
