Comme exemple pratique servant de base à la modélisation, on a pris le cas du quai sur
pieux du port de Marina Bay D’Alger on a procédé à une simulation par éléments finis avec le
logiciel PLAXIS). Dans notre cas, on s’intéresse au chargement statique seulement et une
modélisation à deux dimensions.
À la fin, on s’est intéressé à la sensibilité de la modélisation vis-à-vis des différentes
phases d’exécution des pieux, coulage de la poutre de d’accostage, ainsi qu’aux sollicitations
auxquelles les pieux seront soumis. Et ceci en étudiant les efforts internes et les déplacements
obtenus, en analysant les déformations liées aux interfaces sol-pieux-quai.

Summary:
This work consists of treating the behavior of port structures based on piles and simulating the
interaction of the latter with the contact soil by finite elements with the PLAXIS calculation
code. These works, which are very widespread throughout the world, particularly in areas of
low bearing capacity, are little used in Algeria, despite the certain advantages they present in
relation to the economy of materials, the time required for completion and the low mobilization
of soils. Superficial layers.
To do this, we begin with a study, which consists of listing on the one hand the various types
of port works in general and on the other hand the design methods of these works.
We are particularly interested in boom ports based on piles, in the different means of evaluating
the bearing capacity of an isolated pile, through the determination of the peak resistance of the
pile, as well as its lateral friction; the mechanism of negative and positive friction, and the
behavior of the isolated pile and pile group under lateral loads.
As a practical example serving as a basis for modeling, we took the case of the quay on piles of
the port of Marina Bay of Algiers; we carried out a finite element simulation with the PLAXIS
software). In our case, we are interested in the static loading only and a two-dimensional
modeling.
At the end, we were interested in the sensitivity of the modeling vis-à-vis the different phases
of execution of the piles, casting of the docking beam, as well as the stresses to which the piles
will be subjected. Moreover, this by studying the internal forces and the displacements obtained,
by analyzing the deformations linked to the soil-pile-quay interfaces.
Keywords: Port works, Quay, Piles, Soil-Pile Interaction, Modeling, PLAXIS2D, and Finite
Elements.
