5. Conclusion

In conclusion, retaining walls play a vital role in ground stability and infrastructure safety. The development of innovative technologies, such as Terre Armée ^® and the use of geosynthetics, offers solutions adapted to varied terrains and specific constraints. However, the success of these structures depends on a rigorous geotechnical study, good drainage management and particular attention to the durability of the materials used. The choice of wall type must be guided by a precise assessment of project requirements and soil characteristics, to ensure the safety and longevity of the structures.
