Abstract

Corrosion is a key factor affecting the structural safety of hydraulic gates. Through the image recognition technology of the LBP algorithm, the geometric shape information such as the identification unit and the LBP₁₆² value is clarified, and the degree of disease of the corroded component is quantitatively identified. Combined with the resistance bearing test of the corroded components, the resistance performance of the corroded components exhibits a quadratic parabolic attenuation characteristic with the degree of corrosion disease, and the maximum attenuation of the resistance index in the area with severe corrosion disease exceeds 44.41%, and it presents obvious discreteness and uncertainty. It is an effective technical measure to prevent engineering disasters to strengthen the identification of corrosion disease of the stressed components of the gate, especially the disposal or scrapping of the seriously corrosion diseased area.
