Abstract: Dynamic pile load testing has seen wide applications in estimating pile bearing capacity and checking pile integrity. This paper describes the theory of High Strain and Low Strain Dynamic Testing. Engineering examples are presented in this paper to show the comparison of between dynamic test result and static load test results on both a precast concrete pipe pile and a precast concrete square pile.  Pros and cons of dynamic load testing are also discussed.

Key words: Low Strain, High Strain, Dynamic Pile Tests
