Abstract
High-strain dynamic pile tests using the pile driving analyzer (PDA) and the Case method have been available in Canada for over 15 years. During that period of time, the hardware has evolved considerably but the way the data is interpreted has basically remained the same. The evaluation of the bearing capacity of the tested pile still uses the Case method, with the Case J factor being calculated either from the results of a static load test or, more often, from the results of one or more CAPWAP (Case pile wave analysis program) analyses. A computer program has been developed to estimate the bearing capacity of piles using the dynamic test results produced by the PDA. This program uses direct correlations between PDA data and CAPWAP results. It also includes an artificial intelligence module trained to predict CAPWAP pile capacity. It is not designed to replace the CAPWAP program, but rather to indicate when an additional CAPWAP analysis might be required. Key words : dynamic load test, computer program, artificial intelligence, CAPWAP, Case method.
