Challenge Problems
Push your limits with advanced challenges
If a soil sample experiences a loading of 50 kPa and the dial reading changes from 3.0 mm to 4.5 mm in time intervals t1=1 hour and t2=4 hours, calculate the coefficient of consolidation.
💡 Hint: Focus on finding H first, then using the correct times.
You plotted your data and the primary and secondary lines intersect after 6 hours. If the dial readings correspond to 8 and 12 at those times respectively, what can you infer about the soil's consolidation?
💡 Hint: Consider how readings reflect soil stability over time under load.
