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.
