ABSTRACT

The stability of a sheet pile wall can be influenced by ground movements that induce forces at the interface between the soil and the structure. This phenomenon, known as soil-structure interaction, was modeled by Winkler to determine the structural movements associated with those of the ground. This article focuses on modeling and analyzing the behavior of a sheet pile wall subjected to lateral soil pressure, taking soil-structure interaction into account. An analytical approach, combined with numerical solutions, is applied to examine the behavior of the structure. The approach is based on the Winkler model, also known as the soil reaction coefficient method, which is a method for modeling soil-structure interaction. This model allows the wall to be treated as a self-supporting vertical beam, while the soil-assumed to be elastic and consisting of underconsolidated clay-is modeled as a set of independent springs with a horizontal reaction modulus of . The results show variations in the structure’s behavior under the effect of ground movements. A parametric study was conducted on the soil’s pressuremeter modulus (Ménard modulus) and on the wall’s stiffness to demonstrate the relationship between the properties of the soil and the structure and the structure’s displacement. The variation in the Ménard modulus demonstrates that the stiffer the soil, the greater the reduction in the curtain’s displacement and deflection, which confirms previous theories regarding the behavior of this type of structure.
