Question 1.
What does permeability refer to in soil?
Show hintHide hint
Think about how quickly water drains through different soils.
Question 2.
Why do larger soil particles generally allow for better drainage?
Show hintHide hint
Consider the flow of water through different-sized sand grains.
3Question 3.
What is the effect of larger soil particles on permeability?
- Increase
- Decrease
- No effect
Show hintHide hint
Think about how water moves through gravel versus clay.
4Question 4.
True or False: Increased compaction always increases permeability.
- True
- False
Show hintHide hint
Consider the effects of compressing a sponge.
Question 5.
You are tasked with constructing a roadway. How would you decide on using a soil with large or small particles? Discuss the trade-offs involved in relation to permeability and compaction.
Show hintHide hint
Think about the needs of your engineering project.
Question 6.
Analyze how different compaction techniques might alter the permeability of a given soil type with larger particles. What experimental approach could you use to quantify this effect?
Show hintHide hint
Consider lab testing methods like constant head or falling head permeability tests.
