基于变形的城市桥梁健康监测系统初探

Studying of deformation based urban bridge health monitoring system

国内外不断发生的桥梁跨塌事故,引起人们对桥梁健康监测的日益重视。大跨径桥梁健康监测系统通常大而全且成本高昂,探索研究适合城市桥梁的健康监测系统具有一定的理论价值和现实意义。本文基于某城市桥梁的变形监测和定期检测,尝试提出基于变形的城市桥梁健康监测系统,工程实践表明,该系统操作方便,投资少,能及时进行桥梁安全与预警,可供目前广泛开展的城市桥梁健康状态评估参考借鉴。

Bridge collapse accidents happened in China and abroad have got more and more concern on bridge health monitoring. Long-span bridge health monitoring system is very comprehensive and cost greatly. Therefore, it is a matter of conceptual and practical value to study this system for urban bridge. Based on deformation monitoring and regular detection, this paper presents a bridge health monitoring system based on deformation observation. It is convenient and not expensive. Relevant projects have proved that this method is capable to give bridge safety prior-warning in time. And it should be helpful to the similar projects in urban areas.
