After long-term operation and use of the dam, affected by various external and internal factors, the surface of the dam will produce deformation or even cracks, if not treated in time, it will greatly increase the safety risks of the dam operation. According to previous research, quantum infrared detection can obtain more clear weak information. We use quantum infrared detector to conduct imaging detection on the surface of the dam body. Compared with traditional detection methods, quantum infrared detection has the characteristics of high resolution, high signal-to-noise ratio and high sensitivity, which can improve the detection accuracy and obtain clearer image information. Through post-processing of imaging information, cracks or other deformation and failure information are marked, and risk warning is issued for subsequent engineering construction treatment.
