老旧石拱桥加固结构损伤检测方法OA

In order to address safety hazards such as mortar detachment,cracking,and sinking caused by water flow impact on old stone arch bridges,and to extend their service life,a multi band infrared detection method for structural damage of reinforced old stone arch bridges based on geometric shape reconstruction is proposed.By combining image preprocessing techniques to eliminate interference factors and constructing a high-dimensional pixel matrix,edge detection and refinement techniques are used to restore the geometric shape of the damaged area.By using Gaussian distribution model to conduct in-depth analysis of the reconstructed damaged area,the internal structural characteristics of the damage are revealed.The obtain a multi band infrared detection result that is completely consistent with the actual damage,with the highest loss rate result being 0.071.The detection method proposed in this article can provide technical support for the reinforcement and maintenance of old stone arch bridges.
