Question: What is the primary factor affecting the consolidation settlement of a saturated clay layer?

Options:

Correct Answer: Permeability

Solution:

Permeability is the primary factor affecting the rate of consolidation, as it determines how quickly pore water can escape from the soil.

What is the primary factor affecting the consolidation settlement of a saturated clay layer?

What is the primary factor affecting the consolidation settlement of a saturated clay layer?

Step 1: Understand what consolidation means. It is the process where soil compresses over time due to the weight above it.
Step 2: Know that saturated clay means the clay is fully soaked with water.
Step 3: Realize that when weight is added to the clay, the water inside needs to escape for the clay to settle.
Step 4: Learn that permeability is a measure of how easily water can flow through the soil.
Step 5: Recognize that if the clay has high permeability, water can escape quickly, leading to faster consolidation.
Step 6: Conversely, if the clay has low permeability, water escapes slowly, resulting in slower consolidation.
