摘要 公路桥梁的安全性对社会和经济发展至关重要。传统的桥梁检测方法依赖人工巡检,尽管可靠,但耗时费力,成本高,且存在安全隐患,难以及时发现细微缺陷。随着智能技术的发展,桥梁智能检测技术取得了显著进展。无人机、高分辨率相机和激光雷达等设备结合深度学习算法,实现了实时、动态的桥梁图像采集和病害自动识别,这大大提高了检测效率和准确性,通过三维建模提供详细的桥梁结构信息,减少了维修成本,延长了桥梁使用寿命。尽管智能检测技术具有诸多优势,但仍面临成本高、环境影响大及处理复杂结构和多样化病害的挑战。未来研究应关注多源数据融合、提高检测系统效率、开发智能决策支持系统、提升自动化巡检技术及建立长期监测系统,以提供更加科学和有效的桥梁维护方案。 The safety of highway and bridges is crucial to social and economic development.Traditional bridge detection methods rely on manual inspection.Although reliable,it is time-consuming and laborious,costly,and has hidden safety risks,so it is difficult to find subtle defects in time.With the development of intelligent technology,the bridge intelligent detection technology has made significant progress.UAV,high resolution camera and laser radar equipment combined with deep learning algorithm,realize the real-time,dynamic bridge image acquisition and the automatic disease recognition,which greatly improves the detection efficiency and accuracy,through 3D modeling of the bridge structure information,reduce the maintenance cost,prolong the service life of the bridge.Although the intelligent detection technology has many advantages,it still faces the challenges of high cost,great environmental impact and the treatment of complex structures and diversified diseases.Future research should focus on multi-source data fusion,improve the efficiency of detection system,develop intelligent decision support system,improve automatic inspection technology and establish long-term monitoring system to provide a more scientific and effective bridge maintenance scheme.
