Question 1.
Define compressibility in relation to soil.
Show hintHide hint
Think about how a sponge behaves when pressed.
Question 2.
What is the purpose of the One-Dimensional Consolidation Test?
Show hintHide hint
Consider why engineers need to know about soil behavior under load.
3Question 3.
What is compressibility?
- The ability of soil to expand.
- The tendency of soil to decrease in volume under pressure.
- A measure of soil permeability.
Show hintHide hint
Think about how materials react to being compressed.
4Question 4.
True or False: Peat is considered a highly compressible soil.
- True
- False
Show hintHide hint
Recall what you've learned about different soil types.
Question 5.
You are tasked with designing a road over a peat-rich area. Describe the potential compressibility issues and how you would address them.
Show hintHide hint
Consider stabilization methods and their impact on reducing compressibility.
Question 6.
Calculate the expected compression if the Compression Index (Cc) of a soil is 0.5 and the applied pressure increases by 100 kPa. How much volume change would you expect if the initial void ratio was 0.9?
Show hintHide hint
Recall the relationships in the compression formulas.
