Abstract:
Driven piles have long been one of the primary options when soil conditions require a deep foundation for structure support. Due to the unique characteristics of their installation techniques revealing soil resistance information, they have also been the topic of many studies and research investigations. Dynamic pile testing has been one of those topics for many decades and is now generally implemented on projects routinely utilizing the Pile Driving Analyzer® (i.e., the PDA). Depending on the details of a particular project, the results of PDA testing may be used differently by different engineers, depending on the focus of the quality control and the level of detail desired. This paper will present technical discussions on how the PDA results, in conjunction with CAPWAP analysis, may be utilized for pile ultimate capacity considerations including the discretized shaft resistance and end bearing components. One case history with PDA and CAPWAP analysis output and is presented for discussion.
