Abstract: The paper presents a case study of a power transmission line tower foundation project in Brazil, in which helical piles were used as the foundation solution due to their technical and operational advantages. The aim of the study is to carry out a statistical analysis of the results obtained in the tensile and compressive tests carried out during the execution of the project, evaluating the geotechnical behavior of the foundations and the peculiarities of the soil conditions. The approach takes into account the natural variability of the soils along the route of the line and seeks to identify patterns and correlations that contribute to improving the design and execution of similar projects. The results show a consistency in the load capacity of the piles, even in soils with significant variations, and reinforce the effectiveness of field tests as a tool for validating the performance of foundations. In conclusion, the work will highlight the importance of detailed statistical analyses to optimize the reliability and safety of projects, as well as reinforcing the advantages of helical piles as an efficient solution for transmission line foundations.
