3.2. Field Deposit Prediction

Try these first

1. 1.

   Define consolidation in your own words.

   Hint

   Think about how weight affects soil.

2. 2.

   What is the importance of the drainage path in consolidation?

   Hint

   Visualize water moving through soil.

3. 3.

   What is the main characteristic of consolidation?

   • Increase in soil volume
   • Decrease in soil volume
   • No change in soil volume

   Hint

   Think about how weight affects soil.

4. 4.

   True or False: The log-time method fits a curve that emphasizes linear behavior.

   • True
   • False

   Hint

   What does a logarithmic scale typically show?

5. 5.

   A new soil sample predicts consolidation based on laboratory data indicating it takes 45 minutes for a 20 cm drainage path. Under field conditions, the path length doubles. How would you predict the new consolidation time?

   Hint

   Use the relationship between time and drainage path length to reason it out.

6. 6.

   You experimentally determined that a sample consolidates exponentially. How might you present your findings using both square-root and log-time methods?

   Hint

   Illustrate and clearly label both graphs for comparison.
