Question 1.
What is the purpose of the Square root of time method?
Show hintHide hint
Think about its role in determining soil behavior over time.
Question 2.
What type of scale is used in plotting dial readings?
Show hintHide hint
Consider why a logarithmic scale might be useful in this context.
3Question 3.
What does the Square root of time method help determine?
- Coefficient of tech
- Coefficient of consolidation (Cv)
- Coefficient of compressibility
Show hintHide hint
Focus on the method's primary function in soil mechanics.
4Question 4.
True or False: The Square root of time method requires that time at point Q be four times that at point P.
- True
- False
Show hintHide hint
Recall the specific time ratio used in this method.
Question 5.
A soil sample shows dial readings of 5mm at point P and 9mm at point Q. If time ratio is maintained, calculate the new dial reading at point R located above P.
Show hintHide hint
Use basic arithmetic to find the position of R related to P.
Question 6.
How would you expect the consolidation curve to change if the soil encountered significantly higher stress than previously tested?
Show hintHide hint
Think about how increased pressure affects soil behavior and consolidation.
