Dynamic Soil Compaction

Vincent D. Reynolds, MBA, P.E.


Course Outline

This 6 hour course will cover the design procedures, contracting procedures, and other essential information of dynamic compaction. A quiz is included at the end to aid in understanding the course material.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.

Learning Objective

At the conclusion of this course, the student would have learned the following:

  1. How dynamic compaction is performed with a tamper;
  2. The mass and height dropped for most tampers;
  3. The cost of dynamic compaction for various tamper sizes;
  4. How Rayleigh waves are produced;
  5. Site conditions that can be improved with dynamic compaction;
  6. The greatest use of dynamic compaction;
  7. The various types tests to determine soil properties;
  8. The frequency of ground vibrations produced dynamic compaction;
  9. The effects of vibrations from dynamic compaction;
  10. The most favorable soil conditions for dynamic compaction;
  11. The particle velocity for compacting building rubble;
  12. The effects of the water table on dynamic compaction;
  13. How to determine the depth of soil improvements;
  14. The amount of allowable post-construction settlement during the economic life of a roadway;
  15. Why dynamic compaction is performed outside of the boundaries of the loaded areas;
  16. How to determine the standard penetration resistance after dynamic compaction for sands & gravels;
  17. The range of depth where the maximum improvements occur during the initial stages of tamping;
  18. The recommended cable size for a 20.0 Mg tamper;
  19. The amount of energy needed to densify various sites and soil types;
  20. Various alternatives to dynamic compaction for ground improvements;
  21. How to determine the n value for different soil types;
  22. The most favorable type of material to use for a working mat;
  23. Drops that are needed to achieve compaction; and
  24. How water content can produce soil collapse.

Intended Audience and Benefit

This course is intended for those wanting an understanding of dynamic soil compaction. It could be especially useful for professionals working in Transportation, site design and geotechnical engineering, as well as construction professionals.

This course is designed so that the intended audience will benefit immediately with the information to make intelligent decisions related to dynamic soil compaction.

Course Introduction

Soil Compaction occurs during first stages of construction for highways, runways, taxiways, site development and other land use projects. The degree of soil compaction could easily determine the life of structure simply because all dead and live loads are supported by the soil. Oftentimes new developments or infrastructure are proposed on unstable or compressible soil. These conditions presents the designer with compaction problems that may not be able to be handled exclusively through various traditionally compaction methods.
