Questions & Step-by-Step Solutions

What is the primary cause of secondary compression in soils after primary consolidation is complete?
  • Step 1: Understand that primary consolidation is the initial settling of soil when a load is applied.
  • Step 2: Recognize that after primary consolidation, the soil may still change over time.
  • Step 3: Learn that secondary compression happens because soil particles rearrange themselves slowly.
  • Step 4: Realize that this rearrangement can lead to additional settling, even after the initial consolidation is done.
