Numerical simulation of non-destructive foundation pile tests
New foundation piles are tested after construction for quality control in many European countries as well as overseas. Length and integrity have to be checked. The test of old foundations becomes more and more important in the frame of re-use in urban areas or bridge inspection. Most of the available non-destructive methods (mainly acoustic) are in use since several decades. They work well in many situations. But the interaction with complicated geometries or soil structures is still not fully understood. Numerical simulation provides important insight into wave propagation depending on foundation and soil properties. We use a specially adopted 2D finite integration technique for cylindrical geometries (CEFIT) for our simulations of measurements with the low strain pile integrity testing method and the parallel seismic technique. After solving problems with the modelling of the pile/soil interface we are able to investigate the influence of e.g. pile geometry variations or soil layers. The results are used to improve the interpretation of real data. Various results are presented and compared to data from construction sites and our recently constructed validation piles.
