| Summary: | Historical tunnels, valued for their cultural significance, face challenges in safety and sustainability due to environmental factors and structural weaknesses. Prolonged exposure to humidity and uneven geological pressures often leads to collapses, necessitating effective safety assessments and repair strategies. Traditional structural analysis models are insufficient due to the irregular geometries and unique characteristics of these tunnels. This study leverages advancements in 3D digital technology, focusing on the Shuangrushan Tunnel in Kinmen County, Taiwan, as the research subject. It integrates Global Navigation Satellite System (GNSS), Unmanned Aerial Vehicle Light Detection and Ranging (UAV LiDAR), and terrestrial laser scanner to reconstruct near-true-scale 3D models of the tunnel and its surrounding environment. Combined with geotechnical drilling data, the 3D finite element method (FEM) is applied to simulate structural vulnerabilities, revealing an 80% alignment with on-site damage inspections. These findings enhance the accuracy of safety monitoring systems and provide valuable insights for global preservation efforts, offering a reliable foundation for designing reinforcement measures and maintenance policies. This approach represents a significant step forward in safeguarding historical tunnels for future generations. |
