The aim of this study is to gain a better understanding of the behavior of rigid piles subjected to lateral loading and head moment in clay soil, taking into account soil-structure interaction. In order to establish the behavioral model of the assembly, soil-pile interaction models according to different authors were presented. According to several authors, the soil-pile interface is characterized by the soil reaction modulus. This parameter, which characterizes the interaction between the soil and the structure, depends not only on the mechanical and geometric properties of the concrete, but also on the foundation soil. Within the framework of our work, the model of is used to determine the modulus of reaction. This is a function of the rheological parameters of the soil (and E_M) and the geometric characteristics of the pile. After solving the behavior model of the rigid soil-pile assembly, the Python programming tool was used to perform the parametric analysis. The results showed the significant impact of the interaction model adopted and the forces applied at the pile head. The study shows that soil parameters have a greater influence on foundation behavior than pile parameters. The results also show that the forces applied at the pile head have a non-negligible influence on the behavior model.
