Questions & Step-by-Step Solutions

What is the typical method for predicting settlement in cohesive soils?
  • Step 1: Understand that cohesive soils are types of soil that stick together, like clay.
  • Step 2: Know that when weight is added to these soils, they can compress and settle.
  • Step 3: Use laboratory tests to measure how much the soil will compress. One common test is the oedometer test.
  • Step 4: In the oedometer test, a soil sample is placed in a device that applies pressure to it.
  • Step 5: Measure how much the soil sample compresses under different amounts of pressure.
  • Step 6: Use the data from the test to calculate how much the soil will settle when weight is applied in real life.
