多尺度视角下桥梁损伤检测与服役性能评估研究综述OA

Bridge inspection and service performance evaluation are critical technologies for ensuring the safe operation of bridges.Utilising a multi-scale perspective,the paper systematically reviews the academic progress and future trends in the field of bridge damage detection and assessment.The research is explored from three different scales:macro,meso,and sub-micro.A thorough analysis of the evolution of bridge feature detection methods is presented at the macro level,illuminating the trend of transformation toward rapid detection technologies based on vehicle responses.At the meso-and sub-micro scales,the complexity of bridge surface damage has resulted in research focusing on recognition methods based on computer vision.In terms of service performance evaluation,the extant methods for short-term bridge condition assessment and long-term condition prediction are summarized.The comprehensive analysis shows that the current bridge inspection technology has been effective in identifying bridge damage features.However,future research should still focus on two directions:macro damage identification based on vehicle response and meso-and sub-micro damage identification based on computer vision.Both directions have shown great application potential.Future research should further optimize vehicle-bridge coupled response models and improve their applicability to different forms of macro-scale damage;Study the mapping relationships between meso-and sub-micro-scale damage images and bridge mechanical characteristics;conduct research on multi-scale damage correlation to improve detection accuracy;and explore more practical evaluation methods for bridge service performance based on engineering practice.
