4 cards from this section. Quick, good the night before a test.
Define compressibility in soil.
Think about what happens to soil when you compress it.
What does the Coefficient of Consolidation (Cv) represent?
Consider how quickly a sponge releases water.
What does Cv stand for?
Think of what it means for soil under pressure.
True or False: A high Cc value indicates low soil compressibility.
Think about the implications of compressibility.
A soil sample exhibits a Cv of 0.5 m²/year. If the load is applied and the settlement is monitored over the first year, calculate the expected amount of settlement after one year if the initial thickness was 1 meter.
Use the relationship between Cv, time, and settlement.
A construction project needs to determine the impact of using different soil types on the foundation. Compare and contrast the expected Cc values of sand, silt, and clay soils. Then recommend which soil is best for minimal settlement.
Reflect on how compressibility varies among the soil types.
