Automatic seepage detection in cable tunnels using infrared thermography

Abstract: Seepage in tunnel engineering, especially in underground cable tunnels, is one of the influencing factors in tunnel safety. Seepage directly or indirectly induces many tunnel accidents. The reliable observation and reasonable identification of seepage plays an important role in ensuring the safety of a tunnel. This paper introduces an infrared thermography-based auto-inspection system for seepage in cable tunnels. The leaks whether they are detectable visually or not are identified. The leakage area is accurat… Show more
