1.2. One dimensional theory hypothesis

Try these first

1. 1.

   What is one major assumption of Terzaghi's one-dimensional consolidation theory?

   Hint

   Think about the necessary condition for soil behavior.

2. 2.

   True or false: The volume change of soil is equal to the change in volume of voids.

   Hint

   Recall the second hypothesis discussed.

3. 3.

   What is the consequence of assuming constant permeability in Terzaghi's theory?

   • Inaccurate predictions
   • Better soil design
   • Uniform drainage

   Hint

   Think about changes in soil structure.

4. 4.

   True or False: One-dimensional consolidation is a perfect model for all soil types.

   • True
   • False

   Hint

   Consider the varieties in real-world applications.

5. 5.

   What would happen if a saturated soil layer under a structure experiences a sudden increase in load? Analyze the consolidation process considering Terzaghi’s assumptions.

   Hint

   Think about how quickly water can escape the soil.

6. 6.

   In a construction site, engineers notice varying consolidation rates in different soil layers. How should they design foundations considering Terzaghi’s theory and the observed conditions?

   Hint

   Focus on the implications of varying drainage paths and soil types.
