Questions & Step-by-Step Solutions

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.
