Modelagem numérica do comportamento de fundações profundas e verificação da capacidade de carga de estacas

Abstract

The geotechnical, within the engineering’s universe, presents as an area still fairly recent. That's because there is still much to discover, explore and mainly develop and improve techniques and theories used today. The uncertainties about the ground material involve, in most cases, in studies with low probability of accurate conclusions and generalized, applicable to several cases. This happens easily when it creates a large limit of the search, by restricting to particular cases. Therefore, this study analyzes different methods for determining load capacity in foundation piles proposed in the literature. This is made from a comparison between the methods and a numerical modeling performed in a finite element software, in order to check which one has the closest matches of the computational implementation, once this was powered by real data from a load test. To this end, it was necessary a vast theoretical foundation of the subject, relevant to parameter estimation for the soil types found on the ground. Finally an analysis is made to reach the conclusion most advisable for the case study.
