This paper proposes a numerical simulation of the mechanical behavior of
a reinforced concrete pile foundation under an axial load. In fact, the
foundation of a structure represents the essential structural part of it,
because it ensures its bearing capacity. Among the types of foundation, deep foundation is the one for which from a
mechanical point of view, the justification takes into account the isolated or
combined effects of base resistance offered by the soil bed and lateral
friction at the soil-pile interface; the latter being the consequence of a
large contact surface with the surrounding soil; hence the need to study the
interaction between the soil and the pile in service, in order to highlight the
characteristics of soil which influence the mechanical behavior of pile and
therefore the stability of the structure. In this study,the
reinforced concrete pile is supposed to be elastic, and characterized by a young’s modulus (E)
and a Poisson’s ratio (ν). The soil obeys to a Camclay model characterized by a cohesion (c),
an initial voids ratio (e0), shearing resistance angle (
