Abstract
In situ measurements, carried out in deep excavations during construction, show that the installation of anchor piles to prevent uplift of the formation level slab leads to large deformations in the excavation support works. Currently, it is hardly possible to predict these installation‐related additional loads and they are often quite astonishing. The aim of this article is to present a first numerical model, to predict the additional loads on the subsoil and the excavation works in the vicinity of piling works. The importance of the numerical investigations is described, using the example of the additional deformations measured at Potsdamer Platz during the vibratory driving of anchor piles. In the future however, considerable work will still be required to derive recommendations for excavation work.
