4 cards from this section. Quick, good the night before a test.
What is the void ratio?
Think about the components of soil structure.
Define effective stress.
Recall how water pressure affects soil stability.
What does the void ratio measure?
Think about what spaces in soil contribute to its structure.
True or False: The permanent strain indicates reversible deformation.
Consider what happens to soil when loads are removed.
A soil sample displays a void ratio of 0.4 under a specific effective stress. If the stress increases, predict how the void ratio will change and explain.
Consider the principles of consolidation and void ratio behavior.
Analyze the effects of unloading on a soil structure that originally compresses significantly. What design considerations will engineers need to make for this structure?
Remember how soils behave differently during unloading and reloading.
