ABSTRACT: This paper
delves into the critical aspects of sheet pile walls in civil engineering, highlighting their
versatility in soil protection, retention, and waterproofing, all while
emphasizing sustainability and efficient construction practices. The paper
explores two fundamental approaches to sheet pile design: limit equilibrium
methods and numerical techniques, with a particular focus on finite element
analysis. Utilizing the robust PLAXIS 2016 calculation code based on the finite
element method and employing a simplified elastoplastic model (Mohr-Coulomb),
this study meticulously models the interaction between sheet pile walls and
surrounding soil. The research offers valuable insights into settlement and
deformation patterns that adjacent buildings may experience during various
construction phases. The central objective of this paper is to present the
study’s findings and recommend potential mitigation measures for settlement
effects on nearby structures. By unraveling the intricate interplay between
sheet pile wall construction and neighboring buildings, the paper equips
engineers and practitioners to make informed decisions that ensure the safety
and integrity of the built environment. In the context of the Cotonou East
Corniche development, the study addresses the limitations of existing software,
such as RIDO, in predicting settlements and deformations affecting nearby
buildings due to the substantial load supported by sheet pile walls. This
information gap necessitates a comprehensive study to assess potential impacts
on adjacent structures and propose suitable mitigation measures. The research
underscores the intricate dynamics between sheet pile wall construction and its
influence on the local environment. It emphasizes the critical importance of
proactive engineering and vigilant monitoring in managing and mitigating
potential hazards to nearby buildings. To mitigate these risks, the paper
recommends measures such as deep foundations, ground improvement techniques,
and retrofitting. The findings presented in this study contribute significantly
to the field of civil engineering and offer invaluable insights into the
multifaceted dynamics of construction-induced settlement. The study underscores
the importance of continuous evaluation and coordination between construction
teams and building owners to effectively manage the impacts of sheet pile wall
construction on adjacent structures.
