Thermal Deformation Tracking and Anomaly Detection in Continuous Curved Viaducts Using GNSS Displacement Monitoring with Multi-Point Fixed Metal Bearings

Abstract

This study investigates thermal deformation behavior and anomaly detection in a continuous curved viaduct equipped with multi-point fixed metal bearings using GNSS displacement monitoring. Temperature fluctuations can cause significant deformations, potentially leading to structural anomalies or failures. A GNSS-based monitoring system was implemented to track displacements over time under varying thermal conditions. The study systematically analyzes thermal deformation patterns and identifies deviations that may indicate risks to structural integrity. Long-term GNSS data processing reveals insights into interactions with thermal loads and structural responses. The findings demonstrate the effectiveness of GNSS in real- time deformation tracking, enhancing accuracy in monitoring complex viaduct structures. This research contributes to early anomaly detection and optimized maintenance strategies, improving safety and ensuring the longevity of critical infrastructure. The proposed methodology offers a reliable approach to managing the structural health of curved viaducts, supporting sustainable infrastructure maintenance and long-term operational stability.
