1.1.2. Square root of time method

Try these first

1. 1.

   What is the purpose of the Square root of time method?

   Hint

   Think about its role in determining soil behavior over time.

2. 2.

   What type of scale is used in plotting dial readings?

   Hint

   Consider why a logarithmic scale might be useful in this context.

3. 3.

   What does the Square root of time method help determine?

   • Coefficient of tech
   • Coefficient of consolidation (Cv)
   • Coefficient of compressibility

   Hint

   Focus on the method's primary function in soil mechanics.

4. 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

   Hint

   Recall the specific time ratio used in this method.

5. 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.

   Hint

   Use basic arithmetic to find the position of R related to P.

6. 6.

   How would you expect the consolidation curve to change if the soil encountered significantly higher stress than previously tested?

   Hint

   Think about how increased pressure affects soil behavior and consolidation.
