Proceedings of the 10th International Symposium on Reliability Engineering and Risk Management (ISRERM 2026)

Taiwan is located at the boundary between the Eurasian Plate and the Philippine Sea Plate, resulting in frequent seismic activity and increasing risks to aging underground infrastructure, particularly in liquefaction-prone areas. To address these challenges, Taipei City has mandated Ground Penetrating Radar (GPR) inspections for construction projects to assess subsurface conditions and underground utilities. This study aims to enhance the reliability of GPR in urban subsurface investigations through a combination of literature review, sandbox experiments, and field validation. Controlled indoor sandbox tests and LIDA case data were used to evaluate the accuracy of pipeline detection and material identification. Key parameters of buried pipelines and surrounding soils were analyzed using digital signal processing techniques. Furthermore, GPR data were integrated with 3D modeling to reconstruct spatial distributions of underground utilities. The results demonstrate that the proposed approach improves detection accuracy and provides a practical framework for mapping urban subsurface infrastructure. This study contributes to reducing risks associated with aging underground facilities and supports the development of earthquake-resilient urban infrastructure management.
