Challenge Problems
Push your limits with challenges.
Question 1
Calculate the total stress at a depth of 15 feet with a soil unit weight of 120 lbs/ft³. What would happen if water were to saturate this soil to 10 feet?
💡 Hint: Make sure to account for both the weight of the soil and the contribution of the water above.
Question 2
Explain how excavation to a depth of 20 feet might impact pore water pressure and total stress in a nearby area.
💡 Hint: Consider how soil reacts to sudden removal of load and its effects on water movement.
