**Context**:
Guided waves can propagate over long distances with little loss of energy. They are of potential interest for the non-destructive evaluation and structural health monitoring of slender civil engineering structures (cables, bars, etc.). However, the development of robust monitoring methods faces several challenges. On the one hand, civil engineering structures are usually partially or completely buried in an infinite environment. They are often only accessible to one of their end. On the other hand, the multimodal and dispersive nature of guided waves complicates the interpretation of measurement results, so that their exploitation requires propagation models. In this field, significant progress has been made in recent years at Université Gustave Eiffel through the development of original numerical modeling tools, based on finite element methods dedicated to guided waves, and taking into account various phenomena [1-5]: source, presence of defects, embedment in a solid matrix, curvature of the guide, prestress
