1. UNCONFINED COMPRESSION TEST

Try these first

1. 1.

   What does UCT stand for?

   Hint

   Remember the type of strength being measured.

2. 2.

   What kind of soils are primarily tested using the UCT?

   Hint

   Think about the properties of various soil types.

3. 3.

   What does the acronym qu represent?

   • Unconfined Compressive Strength
   • Ultimate Compression Unit
   • Uniform Compression Weight

   Hint

   Focus on the term related to strength measurement.

4. 4.

   True or False: The unconfined compression test applies lateral pressure to the sample.

   • True
   • False

   Hint

   Recall the definition of 'unconfined'.

5. 5.

   If a soil sample has an initially tested qu of 200 kPa, and after saturation it's found to be 120 kPa, discuss the potential implications for construction at that site.

   Hint

   Think about what saturation does to the stability of structures.

6. 6.

   Explain how the principles of Mohr’s Circle can assist when designing a retaining wall in saturated clay conditions.

   Hint

   Consider how understanding stresses can help in safe design choices.
