Questions and Answers

What is compaction in the context of geotechnical engineering?

  • Densification of soils by removal of air through the application of mechanical energy (correct)
  • Adding air to soils to increase permeability
  • Increasing compressibility of soils
  • Loosening soils to decrease strength
  • Which of the following is NOT a reason why soils at a given site may be less than desirable for the intended purpose?

  • Low compressibility (correct)
  • Weak strength
  • High permeability
  • Highly compressible
  • What is often the most economical alternative for improving the properties of soil at a given site?

  • Using highly compressible soil
  • Relocating the project
  • Stabilizing or improving the properties of the soil (correct)

    Study Notes

    Soil Compaction

    • Compaction is the densification of soils by removal of air through the application of mechanical energy.

    Importance of Compaction

    • Compaction is particularly important when soil is used as an engineering material, such as in the construction of earth dams, highways, airfields, etc.

    Undesirable Soil Properties

    • Soils at a given site may be less than desirable for the intended purpose due to being:
      • Weak (strength)
      • Highly compressible
      • Having a high permeability

    Improving Soil Properties

    • The most economical alternative for improving soil properties is often compaction.
    • There are different techniques for soil improvement, but only compaction will be considered in this course.

    Measuring Compaction

    • The degree of compaction is measured in terms of its dry unit weight.
