Resumo:
The disturbances experienced by the soil owing to the load applied to a deep foundation and its relative behavior consist of long time studied phenomena in civil engineering. Several factors such as the installation methods, the pile geometry, the interactions between soil and structure, the load-transfer mechanisms, the soil movements and the disturbances in the stress and compressibility fields present major challenges that have not yet been completely understood. Numerous advances have been observed throw-out the last decades, in order to investigate these behaviors starting from the different pile instrumentations, the use of calibration cameras and centrifuges and most recently the measurement of the stress and strain fields inside the soil mass in model tanks. Despite the advances the numerical modelling of those processes still faces major challenges. Due to simplified approach used by the Discrete Element Method to simulate large deformation and the dilant non-linear behavior of granular soils, it presents as an excellent tool to investigate these processes without further complications. The present work proposed to evaluate the different behaviors obtained with the variations of installation methods investigated as well as their effects in the results of the Pile Load Test. The disturbances were also evaluated in the different models considered and a basic method to achieve qualitative and quantitative comparisons was discussed. These studies were made possible with the help of the PFC2D and UDEC programs developed by Itasca co.
