21.2. Principles of Soil Sampling

Try these first

1. 1.

   What are disturbed soil samples used for?

   Hint

   Think about tests that don't require soil structure to remain intact.

2. 2.

   Name one method of soil sampling.

   Hint

   Recall the method used for soft soils.

3. 3.

   What type of soil sampling collects samples while altering the soil structure?

   • Disturbed
   • Undisturbed
   • Core

   Hint

   Think about which samples are meant for testing structural integrity.

4. 4.

   True or False: Undisturbed samples are important for strength tests.

   • True
   • False

   Hint

   Consider what happens when soil is disturbed.

5. 5.

   Given a construction project in a coastal area, propose which soil sampling methods would be most appropriate and justify your choices.

   Hint

   Consider soil types and environmental impacts.

6. 6.

   Critically compare the implications of using disturbed samples versus undisturbed samples in a geotechnical study for a high-rise building.

   Hint

   Look into why core samples might be a necessity.
