Question 1

What is the primary goal of the log-time method?

  • To determine soil pH
  • To calculate Cv
  • To assess soil permeability

💡 Hint: Think about the importance of understanding soil settlement.

Question 2

True or False: The horizontal line drawn during the log-time method represents 100% consolidation.

  • True
  • False

💡 Hint: Recall the definitions of d0 and d100.

Challenge Problems

Push your limits with challenges.

Question 1

A soil sample exhibits dial readings as follows: 0% compression at 5 seconds and 60% compression at 20 seconds. Using the log-time method, what would be the expected reading at 80 seconds?

💡 Hint: Visualize the curve and think about how readings progress.

Question 2

In a consolidation test, the data collected yielded values of 0.1 at 10 seconds, 0.4 at 40 seconds, and 1.0 at 120 seconds. Is the log-time method applicable here? Why or why not?

💡 Hint: Examine the pattern of values and consider proportional ratios.
