Keynote lecture: Improving the reliability of pile bearing capacity prediction by the dynamic increasing energy test (DIET)

摘要

The dynamic increasing energy test (DIET) allows the measurement of the dynamic resistance ― displacement curve and the prediction of the static resistance ― displacement curve of the pile-soil system. The variations of energy and work done are evaluated by Hamilton's principle of energy conservation, and this evaluation allows the prediction of the dynamic failure load of the system. The usefulness of this approach is confirmed by the good correlation between the results of the DIET and of the static load test.
