Industry Application
1. Application Background
Tunnel construction, inspection, and maintenance require accurate and comprehensive spatial data throughout the entire lifecycle of infrastructure assets. From excavation quality control and as-built documentation to deformation monitoring and renovation planning, reliable 3D measurement data plays a critical role in ensuring construction quality and operational safety.
However, complex tunnel environments, including limited visibility, confined spaces, irregular structures, and restricted working windows, create significant challenges for traditional surveying methods. Efficiently capturing complete tunnel geometry and maintaining consistent data records remain essential for improving engineering accuracy and reducing operational risks.
2. Challenges in Tunnel Surveying
Limited Coverage with Traditional Measurement Methods
Conventional surveying methods, such as total stations and profile measurement instruments, typically rely on discrete measurement points or cross-sections. This approach provides limited spatial coverage and may miss critical details such as local deformation, lining defects, pipeline clearance issues, and structural changes.
Difficult and Unsafe Field Operations
Tunnel environments are often challenging, with limited access, poor lighting, humidity, dust, and restricted working space. Manual measurements in high or narrow areas can increase safety risks and require significant manpower, especially during short maintenance windows.
Lack of Continuous Digital Records
Traditional inspection workflows often produce fragmented drawings, reports, and photographs. Without a unified 3D reference model, multi-period comparison of deformation, settlement, and structural changes becomes difficult, limiting effective lifecycle management.
