Question 1.
What is the void ratio if a soil has 4 cubic meters of voids and 2 cubic meters of solids?
Show hintHide hint
Use the formula: e = V_v / V_s.
Question 2.
How does an increase in void ratio affect permeability?
Show hintHide hint
Think about how space for water affects flow.
3Question 3.
What does the void ratio represent?
Show hintHide hint
Think about how voids and solids interact in a soil sample.
4Question 4.
Is a higher void ratio usually associated with higher permeability?
- True
- False
Show hintHide hint
Consider how spaces in the soil affect water flow.
Question 5.
A soil has a void ratio of 4. If the soil's specific weight is 18 kN/m3, calculate the volume of voids and the volume of solids in a 1 m³ soil sample.
Show hintHide hint
Use the formula: V_v = e * V_s.
Question 6.
Analyze how a void ratio change from 0.3 to 0.6 might impact the drainage capability of a building site over time.
Show hintHide hint
Reflect on soil behavior under increased permeability conditions.
