随着我国桥梁服役期的不断增长，其安全性、耐久性及维护管理的问题日益严重，安全保障问题也日益突出。本文调研了国内外桥梁结构安全保障科技发展的现状与趋势，阐述了我国桥梁安全保障领域的现状与面临的挑战，分析了我国桥梁安全保障技术、措施和政策的现状、优势以及与国外的主要差距，并在此基础上提出关于我国桥梁安全保障政策、技术和措施方面的思考。本文的研究结果可为我国重大基础设施结构安全保障计划的制定提供参考。

With the continuous increase in bridge service life, problems regarding the safety, durability, and maintenance management are becoming increasingly serious. Safety guarantee issues will become increasingly prominent. In this study, the current safety situation and trends in bridge structure are investigated, along with domestic and foreign scientific and technological developments. The present situation of bridges in China in the field of safety and its challenges are also discussed in this paper. The status and advantages of China’s bridge security technologies, measures, and policies, as well as the main differences between China and foreign countries are analyzed. Furthermore, policies, technologies, and measures for bridge safety and security are proposed. This paper can provide a reference for the development of a major infrastructure security plan.
