TUDa Geotechnical Test Pit
Institute of Geotechnics, Technical University of Darmstadt, Darmstadt / Germany
Scope
The TUDa Geotechnical Test Pit (GTP) is a testing facility mainly for studying soil-pile interaction, although in principle, investigation of other geotechnical problems is also possible. The facility allows for near to full-scale testing (e.g., micropiles), as well as medium to large-scale model testing, thus being able to close the gap between small-scale testing, on one hand, and very rare and expensive in-situ testing, on the other. The facility also overcomes some of the limitations of centrifuge testing such as scalability of the soil/soil grain. As such, phenomena that are usually difficult to observe, as for instance soil-water interaction, can be better investigated. With its capability, the GTP can provide valuable contribution in the testing and validation of existing physical theories and numerical models, as well as in the development of new ones.
