Abstract:
Dynamic Load Test (DLT) on driven piles has been performed routinely all over the world. Recently, 100% testing has become a norm in several projects where every single pile is dynamically load tested. Most piles are of uniform sections, making the data analysis straight forward. The CASE method, which has been used for the last 50 years, is only applied to uniform piles. Until 2021, this method had been the only available method in the field, due to the lack of a rigorous instant signal matching analysis for non-uniform piles. The field monitored pile driving stresses are also inclusively relied upon the CASE method. This shortcoming can lead the field engineers to incorrectly monitor the wrong values for driving stresses as well as the ultimate bearing resistances for non-uniform piles. However, when the pile is highly non-uniform, the data analysis is much more challenging. The presentation highlights recent advances in instant Signal Matching Analysis on non-uniform piles, allowing field engineers to correctly monitor stresses and resistances of non-uniform piles in real time.
