Question 1.
What is relative density?
Show hintHide hint
Think about the soil's current state compared to its extremes.
Question 2.
Define the angle of friction for soils.
Show hintHide hint
Consider its role in stability.
3Question 3.
What does relative density indicate?
- Soil's moisture content
- Soil's compactness
- Soil's drainage capability
Show hintHide hint
Think about how packed the soil is.
4Question 4.
True or False: Higher relative density always results in lower angles of friction.
- True
- False
Show hintHide hint
Remember the relationship between density and stability.
Question 5.
A construction site has three soil samples: one with a relative density of 30%, another at 50%, and the last at 70%. Determine which sample is likely to have the highest angle of friction and explain why.
Show hintHide hint
Think about how density influences resistance to sliding.
Question 6.
If a geotechnical analysis reveals an angle of friction of 45 degrees for a specific coarse-grained soil at a relative density of 75%, what implications does this have for a new foundation?
Show hintHide hint
Consider the relationship between load capacities and stability.
