It has been believed that the static load test is the most reliable method to obtain the load-settlement relation of a pile. Most static load tests are conducted using reaction piles as the reaction system. However, some researches point out that the influence of the reaction piles on the measured load-settlement relation may not be neglected, and that an analysis of the measured data is required to obtain a true load-settlement of the. From this point of view, the dynamic load testing or the rapid load testing may not be necessarily inferior to the static load test, considering cost and time performance of the dynamic load test as well. In this study, a new computer program for analysing the stress-wave propagation phenomena in pile driving was developed using a finite difference scheme and rational soil resistance models. Verification analyses of the proposed method are conducted first, and then the developed method is applied to the dynamic and static load tests on an end-bearing concrete pile.
