Question: In a consolidation case study, what is the primary mechanism by which soil settles over time?

Options:

Correct Answer: Volume change due to pore water expulsion

Solution:

Consolidation involves volume change due to the expulsion of pore water, leading to settlement over time.

In a consolidation case study, what is the primary mechanism by which soil settles over time?

In a consolidation case study, what is the primary mechanism by which soil settles over time?

Step 1: Understand that soil is made up of solid particles and water in the spaces between them, called pore spaces.
Step 2: When weight is added to the soil (like buildings or roads), it compresses the soil.
Step 3: As the soil compresses, the water in the pore spaces is pushed out.
Step 4: This expulsion of water causes the soil to lose volume.
Step 5: As the volume decreases, the soil settles, which is known as consolidation.
Step 6: This process happens over time, so the soil continues to settle gradually.

Consolidation – The process by which soil decreases in volume over time due to the expulsion of pore water, resulting in settlement.
