Question 1

What is the primary purpose of plotting dial readings?

  • To visualize consolidation
  • To measure soil density
  • To calculate soil moisture

💡 Hint: Remember the relationship between time and consolidation.

Question 2

True or False: A tangent line can intersect the curve at multiple points.

  • True
  • False

💡 Hint: Reflect on the definition of a tangent.

Challenge Problems

Push your limits with challenges.

Question 1

If soil consolidation data indicates a dial reading progression from 1.0 mm to 2.2 mm over a time interval of 36 minutes, how would you derive the change in consolidation rate? Illustrate it on a square-root time plot.

💡 Hint: Focus on the differences between readings and analyze the square-root values.

Question 2

Given a scenario where a soil deposit is 1 meter thick, and the laboratory results suggest 10 days for full consolidation at a specific loading condition, create a model predicting the time under field conditions using the dial reading technique discussed.

💡 Hint: Consider how field conditions differ from laboratory scenarios.
