1.9. Behavior Beyond Point C

Try these first

1. 1.

   What is effective stress in soil mechanics?

   Hint

   Think about how water affects soil.

2. 2.

   Name the path followed during initial compression.

   Hint

   Consider the early loading state.

3. 3.

   What does the virgin compression curve represent?

   • It shows elastic recovery
   • It shows maximum compression behavior
   • It shows soil's expansion

   Hint

   Think about what happens when soil is loaded heavily.

4. 4.

   Is it true that unloading a soil sample results in elastic recovery?

   • True
   • False

   Hint

   Consider what happens when you release pressure.

5. 5.

   Analyze a scenario where a building is constructed on previously loaded soil. Explain how the behavior beyond point C can lead to structural issues.

   Hint

   Consider how the building load interacts with prior soil behavior.

6. 6.

   Given a consolidation curve with specific void ratios and stress points, calculate the expected permanent strain for a hypothetical soil sample.

   Hint

   Refer back to how permanent strain is defined based on loading cycles.
