Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What does the void ratio represent in soils?

💡 Hint: Think about how we differentiate solid and empty spaces in soil.

Question 2

Easy

What occurs when soil is unloaded?

💡 Hint: Remember the CD path we discussed.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the virgin compression curve indicate?

  • It shows the initial compression.
  • It indicates significant compression beyond a limit.
  • It represents the unloading path.

💡 Hint: Where do we see heavy compression taking place on the graph?

Question 2

Hysteresis loops are formed during which processes?

  • True
  • False

💡 Hint: Consider if these loops appear when there's a difference in stress paths.

Challenge Problems

Push your limits with challenges.

Question 1

A load is applied to a soil sample which undergoes a certain amount of compression. If the load is then removed, calculate how much strain remains in the soil given a known elastic modulus and previous void ratio.

💡 Hint: Break down the calculations into elastic and plastic components.

Question 2

You have two soil samples; one follows a distinct compression curve while the other has similar parameters but shows hysteresis. Discuss the implications of these differences on sub-grade performance when loaded.

💡 Hint: Compare and contrast their compressibility behavior as structural foundations.
