2.1. The basis for this method is the theoretical (Uz) versus log Tv curve and experimental dial gauge reading and log t curves are similar.

Try these first

1. 1.

   What does Cv stand for in soil mechanics?

   Hint

   Think of how soil behaves when loaded.

2. 2.

   What is the main purpose of the Log-time method?

   Hint

   It involves creating plots based on time.

3. 3.

   What does Cv represent in soil mechanics?

   • Consolidation Velocity
   • Coefficient of Consolidation
   • Compressibility Variation

   Hint

   It's related to consolidation rates.

4. 4.

   True or False: The Log-time method uses a linear scale for plotting.

   • True
   • False

   Hint

   Recall the method's key properties.

5. 5.

   Given the dial readings of 2 cm and 4 cm at t1 and t2 respectively, calculate the percentage of consolidation.

   Hint

   Break down the percentages using the consolidation equation.

6. 6.

   If a soil sample shows 100% consolidation at time t = 12 hours, what can be inferred about the sample's consolidation behavior?

   Hint

   Consider how time influences pore water pressure.
