Challenge Problems
Push your limits with challenges.
Question 1
If soil total stress is 100 kPa and the pore water pressure is 30 kPa, what is the effective stress?
💡 Hint: Use the effective stress formula.
Question 2
A soil layer has a unit weight of 20 kN/m³. Calculate the total stress at 15 meters depth and the change in effective stress if the total stress increases by 25 kPa and pore water pressure increases initially by 10 kPa.
💡 Hint: Identify total stress first, then apply changes based on load and drainage!
