Résumé:
Piles have been used effectively in many applications that involve, on the one hand, improving
the characteristics of soft soil and increasing its bearing capacity and, on the other hand,
reducing settlements, especially in the case of the reinforcement of existing foundations.
Pile buckling is currently one of the more complicated geotechnical problems that engineers
and researchers have to deal with. This problem has become a very interesting research topic.
A Finite Element Method (FEM) to study this phenomenon is very promising because of the
many possibilities offered by this method to model the actual pile behavior. The software can
be used in this study because of its versatility and flexibility. Abaqus is characterized by its
ability to solve problems realistically, particularly the treatment of contact in order of modeling
the real behavior of this type of structure.
The thesis consists in a numerical modeling of the soil-pile interaction under an axial static
load applied at the head of the pile. In addition, a parametric study was carried out. Several
parameters have been modified to evaluate their effects on the critical buckling load of the
fully embedded pile.
