observation based on the behaviour of the three smart reinforcements, it can be concluded that the landslide is currently in a stable condition, thus affirming the effectiveness of the various interventions implemented on site. 5. Conclusion The solution proposed in this study integrates innovative monitoring technologies aimed at enhancing our understanding of the structural behavior of composite anchors in absorbing horizontal stresses and mitigating the forces that trigger landslide movements. This paper presents the initial findings from a novel experimental site, where composite anchors were strategically deployed within an active landslide zone to impede its kinematic progression. By incorporating DFOS within these anchors, the evolution of traction over time and along their length could be effectively monitored. The results achieved so far have demonstrated promise, suggesting the potential efficacy of the monitored composite anchors in mitigating landslide activity. However, it is imperative to recognize that these findings represent preliminary observations. This underscores the necessity for further comprehensive validation to confirm the reliability and robustness of the monitoring system, as well as its suitability for assessing the long-term performance of these anchors and potentially formalizing the Observational Method. This could include the possibility of conducting new intervention phases as necessary, based on the conditions of the monitored reinforcements and other monitoring instruments on site.
