Questions & Step-by-Step Solutions
What is the term for the ratio of the change in void ratio to the change in effective stress during consolidation?
Step 1: Understand what void ratio means. It is the ratio of the volume of voids (spaces) to the volume of solids in a soil sample.
Step 2: Know what effective stress is. It is the stress that contributes to the strength of the soil, calculated by subtracting pore water pressure from total stress.
Step 3: Learn about consolidation. It is the process where soil volume decreases due to the expulsion of water from the voids when stress is applied.
Step 4: Identify the change in void ratio. This is how much the void ratio decreases during consolidation.
Step 5: Identify the change in effective stress. This is how much the effective stress increases during consolidation.
Step 6: Understand the ratio. The compression index (Cc) is the ratio of the change in void ratio to the change in effective stress.
Step 7: Conclude that the term you are looking for is the compression index (Cc).
