Question 1.
What does the Swelling Index measure?
Show hintHide hint
Think about how soil reacts to pressure.
Question 2.
Define effective stress.
Show hintHide hint
Consider how stress affects soil strength.
3Question 3.
What does the Swelling Index indicate in soil?
- Compression measure
- Volumetric change measure
- Material strength measure
Show hintHide hint
Think about the volume changes with stress.
4Question 4.
Effective stress is equal to total stress minus what?
Show hintHide hint
Recall the definition of effective stress.
Question 5.
A geotechnical engineer is evaluating two different clay sites for a large commercial building. Site A has a Swelling Index of 0.1, while Site B has an index of 0.2. Discuss the potential risks and design strategies he should consider for each site.
Show hintHide hint
Consider design adaptations for each site's swelling potential.
Question 6.
Given an e-log σ' plot for a certain clay, the slope changes from steep to flat. What could this indicate about the soil's swelling potential and how should the construction team adjust their approach?
Show hintHide hint
Think about how slope relates to material performance and adjustments needed in construction.
