隧道衬砌渗漏水红外特征模拟试验及图像处理
Simulation Experiment on Infrared Radiation Feature of Tunnel Lining Seepage and Image Processing
摘要
Abstract
To explore the characteristics of seepage defects in underground cable concrete tunnels, we simulated water seepage on custom-made cement blocks with point-like,linear and hollow-like defects. This orthogonal test is aimed to explore the infrared radiation law of cement block leakage with the change of defect form,defect size and leakage flow rate. The features of infrared image and the variation rule influenced by flow rate and defect size were obtained through the later image processing and area extraction. The experimental results show that the seepage characteristics of the test specimens with different seepage patterns are different, and the leakage area increases linearly with the increase of the leakage water flow under certain other conditions,however,the size of the defect has little effect on the area of the leaking water in the case of linear defects. The study provides the basis for the rapid detection of leaking water in practical tunnel.关键词
