2.2. Steps

Try these first

1. 1.

   What does Cv stand for?

   Hint

   Think about what happens to soil under load.

2. 2.

   Which method uses a logarithmic scale for time?

   Hint

   It's the method we are focusing on today.

3. 3.

   What does the Log-time method utilize for analyzing soil consolidation?

   • Linear time scale
   • Logarithmic time scale
   • Square root time scale

   Hint

   Contemplate the type of graph we discussed in class.

4. 4.

   True or False: The coefficient of consolidation is measured in mm/min.

   • True
   • False

   Hint

   Think about how coefficients are typically represented.

5. 5.

   A soil sample shows a dial reading of 10 mm after 2 minutes and 22 mm after 8 minutes. Plot these points and find Cv.

   Hint

   Start with identifying t1 and t2, then calculate the difference.

6. 6.

   If a consolidation curve intersects the dials at 0%, 50%, and 100% at specific times, explain how you would analyze these points for practical applications.

   Hint

   Relate readings to real-world scenarios like park benches or buildings.
