4 cards from this section. Quick, good the night before a test.
What does the coefficient of consolidation (Cv) represent?
Think about how soil reacts to pressure.
Define 0% consolidation.
Consider what happens before any weight is applied.
What is the purpose of the Logarithm of Time method?
Think about why we measure consolidation in soil.
Is 0% consolidation a pre-loading state?
Remember what happens before any load is applied.
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.
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?
Consider how readings reflect soil stability over time under load.
