Concrete slab is an important hydraulic structure of hydropower station.In order to investigate concrete defects,comprehen-sive testing needs to be carried out.Aiming at the problems of low efficiency and high risk of traditional inspection,thermal imaging tech-nology is used to effectively inspect and identify cracks in concrete slab of hydropower stations.The application of infrared thermal imaging technology in crack detection is analyzed theoretically,and through the numerical simulation technology of the machine rational verifica-tion.This method has been applied in Nangong 1 Hydropower Station in Laos,and the infrared thermal imaging technology is used to con-duct a comprehensive survey of concrete panel cracks,so as to provide necessary technical support for the safety detection of water conser-vancy and hydropower structures.
