In order to quickly identify and extract the water seepage characteristics of cable tunnel, the equipment based on infrared thermal imaging technology for tunnel water seepage detection is studied.The thermal images of the axial and radial direction of the tunnel wall are taken by infrared thermal imaging, and the water seepage characteristics are obtained by analyzing the thermal images. And then the actual application effect of the equipment is testified by taking a section of Chenglang Cable Tunnel in Ningbo for example. The test results show that the equipment can work effectively, and the extracted water seepage characteristic is with high accuracy.
Key words: infrared thermography; cable tunnel; water seepage detection
