The activities are integrated with change management tools and methodologies adopted in the Ansfisa safety management system, to support the transition towards a new operational paradigm in which work zone planning coexists with user and worker safety as well as operational continuity.

Within this framework, a suite of vibration-based damage indicators, ranging from modal analysis metrics to purely data-driven features, was explored. Initially, statistical features were analyzed to identify deviations from a healthy baseline. These were complemented by unsupervised learning methods that capture subtle, nonlinear response variations indicative of stiffness loss. Subsequently, output-only modal identification techniques were employed to estimate modal parameters, thereby enabling modal tracking over time. Modal indicators provide physically interpretable trends when seeking a monotonic linkage to damage, whereas learning-based features exhibit high sensitivity to early, nonlinear response changes. These complementary indicators were used to derive hybrid damage metrics that combine the robustness of physics-based modal parameters with the adaptability of data-driven features.

The site is characterized by soft clay layers exceeding 100 meters in depth, where ongoing creep settlements generate significant long-term downdrag loads on the friction piles. Four open-ended steel piles, 220 mm in diameter and 78 m long, were instrumented with Brillouin-based distributed strain sensing (DSS) cables fixed to the pile exterior using custom-made mechanical clamps at 2-m intervals.

The results reveal a clear negative skin friction pattern, with peak strains occurring at 15–30 m depth depending on pile location, and show differences in downdrag magnitude between perimeter and interior piles consistent with finite element predictions from PLAXIS 3D.

In critical zones such as turnouts and track discontinuities, conventional inspection methods mainly capture geometric and kinematic parameters and fail to represent the load interactions governing deterioration. Continuous monitoring of loads is therefore essential for predictive maintenance. This study investigates the applicability of piezoresistive sensors for load monitoring in railway infrastructure, focusing on their integration into rail pads. Experimental tests using piezoresistive sensors were conducted under static and dynamic loading, considering frequencies between 1–20 Hz, temperatures from −20 °C to +40 °C, and long-term behaviour up to 300,000 load cycles. Both individual sensors and sensor-integrated rail pads (SIRP) were evaluated, including simulated train passage scenarios. The results show a clear frequency dependency with decreasing sensitivity at higher frequencies. Temperature effects were moderate at low temperature changes but reasonable at higher temperatures changes. Long-term tests revealed drift and sensitivity degradation over time. Despite these effects, good agreement with reference measurements was achieved, and reliable performance was demonstrated for the SIRP. The findings indicate that piezoresistive sensors are a promising solution for measuring load transfer in railway infrastructure. However, their application requires consideration of frequency effects, temperature dependency, and long-term drift, as well as appropriate calibration strategies to ensure reliable performance under field conditions.</div></div>","PeriodicalId":20518,"journal":{"name":"Procedia Structural Integrity","volume":"85 ","pages":"Pages 95-101"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149067900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
