2 cards from this section. Quick, good the night before a test.
What does Cv stand for in soil mechanics?
Think about what measures soil behavior under stress.
What is the first step in the log-time curve fitting method?
Consider what type of scale is used.
What does the coefficient of consolidation (Cv) measure?
Remember it relates to stress and settlement.
True or False: The logarithmic scale compresses large time data into a manageable graph.
Consider why we might choose a log scale.
A soil sample shows dial readings of 0.1 mm at t1 (1 hour) and 0.4 mm at t2 (4 hours). Calculate the difference and interpret it in terms of consolidation percentage.
Think about how these differences relate to the total expected settlement.
Considering a log-time graph, point P shows a reading of 0.2 at log t1 and point Q shows 0.5 at log t2. How do you determine the readings for 0% and 100% consolidation?
Refer back to how intersections define those consolidation limits.
