1.1. Types of Triaxial Tests

Try these first

1. 1.

   What is the purpose of a triaxial test?

   Hint

   Think about soil mechanics.

2. 2.

   Name the three types of triaxial tests.

   Hint

   Focus on drainage conditions.

3. 3.

   What type of triaxial test allows drainage throughout?

   • Consolidated-drained
   • Consolidated-undrained
   • Unconsolidated-undrained

   Hint

   Look at the drainage conditions.

4. 4.

   True or False: The shear strength parameters (c and φ) can be determined from Mohr's circles.

   • True
   • False

   Hint

   Consider the role of stress analysis.

5. 5.

   During a consolidated-undrained test on a saturated clay, the axial stress is increased significantly. Predict the changes in pore pressure and effective stress.

   Hint

   Consider the principles governing pore pressure relationships.

6. 6.

   Design a brief experiment using triaxial tests to compare the cohesion values of two different soils: a sand and a clay. Discuss potential challenges.

   Hint

   Focus on how soil type influences test protocols.
