Challenge Problems
Push your limits with advanced challenges
A construction site has soil which you estimate will take approximately 9 months to consolidate based on lab tests. If the field conditions differ significantly, how might that influence your predictions?
💡 Hint: Consider how field pressure and drainage differ from lab scenarios.
During a consolidation test, the dial readings indicate that consolidation reaches 50% in 2 months. If we continue to monitor and observe deterioration in drainage conditions, how might this affect our initial square-root analysis?
💡 Hint: How might drainage affect the time needed for consolidation?
