Demonstrator Experiments on Significant Effects During Pile Installation
Benchmark tests for the numerical simulation of pile installation require clearly defined boundary value problems with corresponding experimental data. These experiments have to provide quantitative information on the soil deformations and stresses. Large scale model tests in dry, granular soil were carried out for this purpose. The interface testing device, that is used for the tests, allows the investigation of selected aspects of pile penetration. The normal and shear forces on the pile structure are measured. The displacements in the surrounding soil zone can be evaluated via Digital Image Correlation (DIC). The test results concentrate on the interface behavior between the soil and the pile and the evolution of stresses and deformations around the pile tip. For rough pile surfaces the occurrence of dilatancy effects in the pile-soil interface is shown. The localization of deformations in the post-peak phase is analyzed for monotonic and cyclic test paths. The influence of the pile driving mode on the evolution of stresses around the pile tip is demonstrated.
