Advantages of Dynamic Pile Testing
Efficient pile design requires an understanding of the engineering properties of the site, the pile, and the complex changes that occur during installation.Engineers usually specify tests to verify the resistance and the behavior of the hammer-pile-soil combination. Static testing requires significant time and expense. A dynamic test monitors the response of the pile-soil system during hammer impact, investigates installation parameters and resistance, and confirms pile integrity. The usability and reliability of dynamic tests have improved with better instrumentation and computing capabilities. Dynamic tests are relatively inexpensive, cause only minor delay to the project, can be performed on any accessible pile, and are now routinely used for both driven and drilled piles. An impact weight of only 1.5% of the desired static resistance provides a low-cost alternative when testing high-capacity piles. Multiple restrikes allow the engineer to investigate changes in driven pile resistance with time and improve the foundation design. A refined wave equation analysis using the dynamic test results provides reliable installation criteria. This paper discusses the advantages of dynamic testing, with specific examples to illustrate its value to verify static resistance, to investigate time effects on resistance, to refine installation criteria, and to address quality control issues.
