摘　　要：基于北京市市管桥梁的基础资料和技术特征,通过统计桥梁的建设时间、设计荷载和结构特点,发现其在结构安全性、耐久性和使用功能上存在显著差异。为了确保桥梁的长期安全与稳定,本文提出了定期检测与评估、定期维护与保养及应急维修管理等策略,借鉴了美国、日本和德国在桥梁管理方面的经验,结合新材料和新技术的应用,如高强度钢、高性能混凝土、碳纤维增强复合材料以及智能检测和维护技术,提升桥梁的承载能力和使用寿命,并实现实时监控;最后针对桥梁的未来发展提出了重点研究方向,包括桥梁抗震、耐久性、智能化管理信息系统及新材料技术等。This article is based on the basic data and technical characteristics of bridges managed by the Beijing Municipal Government.Through statistical analysis of the construction time,design loads,and structural features of bridges,it is found that there are significant differences in their structural safety,durability,and functional use.To ensure bridges'long-term safety and stability,this article proposes strategies such as regular inspection and evaluation,regular maintenance and upkeep,and emergency repair management.Drawing on the experience of the United States,Japan,and Germany in bridge management,combined with the application of new materials and technologies,the bearing capacity and service life of bridges are improved,such as high-strength steel,high-performance concrete,carbon fiber reinforced composite materials,and intelligent detection and maintenance technology,and real-time monitoring is achieved.Finally,future key research directions are proposed,including bridge seismic resistance,durability,intelligent management information systems,and new material technologies.
