Challenge Problems

Push your limits with challenges.

Question 1

You are assessing a site for a new building on cohesive soil. If it was compacted wet of optimum moisture, what mitigation strategies could you propose to improve soil performance?

💡 Hint: Reflect on ways to improve compacted soil performance under different moisture conditions.

Question 2

Calculate the expected settlement for two scenarios: soil compacted dry and compacted wet. Define parameters for each scenario and what measurements you'd need.

💡 Hint: Consider factors like initial density and void ratios for your calculations.
