Challenge Problems
Push your limits with challenges.
Question 1
You have a soil layer with a depth of 12 m, total stress of 36 T/m², and pore water pressure of 15 T/m². Calculate the effective stress. Discuss the implications of pore water pressure changes on stability.
💡 Hint: Apply the effective stress equation to analyze stability.
Question 2
A project involves excavating to a depth of 5 m in an area where the water table is at 3 m. Calculate the effective stress at the bottom of the excavation, and explain what could happen if the water table rises.
💡 Hint: Be careful to consider layers above and any changing conditions!
