Challenge Problems
Push your limits with challenges.
Question 1
A soil column has a total stress of 50 kPa at a depth below a rising water table. If the pore water pressure is calculated at that depth to be 20 kPa, what is the effective stress?
💡 Hint: Use the effective stress equation to solve.
Question 2
Consider an upward water flow scenario with a hydraulic gradient approaching 1. What implications would this have on the stability of a sand layer?
💡 Hint: Think about how it impacts weight support.
