Questions & Step-by-Step Solutions

What is the effect of preloading on settlement?
  • Step 1: Understand what settlement means. Settlement is when the ground sinks or lowers over time due to weight on it.
  • Step 2: Learn about preloading. Preloading is when a temporary weight is placed on the ground before the actual building or load is added.
  • Step 3: Know why preloading is used. It helps to compress the soil and make it stronger, which reduces the amount of sinking that happens later.
  • Step 4: Realize that preloading speeds up a process called consolidation. This is when water in the soil is pushed out, making the soil denser.
  • Step 5: Remember that by using preloading, we can make sure the ground is more stable and less likely to settle after the building is finished.
