摘要: Seepage in tunnel engineering, especially underground cable tunnels, is one of the influencing factors safety. directly or indirectly induces many accidents. The reliable observation and reasonable identification seepage plays an important role ensuring safety a tunnel. This paper introduces infrared thermography-based auto-inspection system for tunnels. leaks whether they are detectable visually not identified. leakage area accurately calculated to make quantitative analysis. objective assessment documents (in PDF format) exported need skilled inspectors reduced. results field trail indicate that automatic detection can greatly improve efficiency (the speed increased by 2.67 times), save manpower (it needs only two using this instead four traditional method) material resources, safety, all which great importance engineering.
