4.3.2.2. Triaxial Compression Test

Try these first

1. 1.

   What are the two main parameters measured in the Triaxial Test?

   Hint

   Think about what two properties are critical for understanding soil mechanics.

2. 2.

   Which type of Triaxial Test doesn't allow drainage?

   Hint

   Consider which test is performed rapidly under high pore pressures.

3. 3.

   Which type of Triaxial Test allows drainage throughout the last testing phase?

   • Unconsolidated Undrained
   • Consolidated Undrained
   • Consolidated Drained

   Hint

   Think about which type allows the soil to fully stabilize.

4. 4.

   True or False: The Triaxial Compression Test measures the pore pressure of the soil.

   • True
   • False

   Hint

   Consider the role of water within soil under loading conditions.

5. 5.

   A soil sample exhibits a cohesion of 35 kPa and a friction angle of 28 degrees. If subjected to a vertical load of 70 kPa, would this sample likely fail? Justify your reasoning based on soil mechanics principles.

   Hint

   Consider the relationship between cohesion, friction angle, and applied loads.

6. 6.

   In what scenarios would you prefer to perform a CU test over a UU test, and why?

   Hint

   Think about the importance of drainage and load timing in your project.
