Abstract: The purposes the dynamic compaction are increasing the bearing capacity of the existing foundation soils, reducing the potential total and differential settlements. It is critical to study the effect of the dynamic compaction. This paper reviews the methods of improving the bearing capacity and methods of evaluating the dynamic compaction influencing depth. Different evaluation methods are compared with the field results. Factors that affecting the dynamic compaction and parameters that for the dynamic compaction result evaluation are also presented in the paper.

Key words: Dynamic Compaction, Bearing Capacity, Effective Depth
