桥梁智能化健康监测研究现状分析

Analysis on The Research Status of Bridge Intelligent Health Monitoring

随着我国经济的高速发展,桥梁作为重要的基础设施得到迅速发展,然而由于设计理论不完善、施工缺陷、材料老化、荷载作用、环境侵害和突发灾害等原因造成桥梁坍塌事故时有发生。因此,通过桥梁健康监测及时发现桥梁安全隐患是避免桥梁安全事故的有效手段。本文阐述了桥梁的智能化健康监测的研究背景、意义及健康监测系统的概念,系统叙述了桥梁健康监测系统国内外的研究现状,发展进程及系统的各个组成部分。重点讨论了当前监测系统中的不足,为未来健康监测系统的研究提供有益的参考。

With the rapid development of China economy, bridges have developed rapidly as an important infrastructure. However, due to imperfect design theory, construction defects, material aging, load, environmental damage and sudden disasters and other reasons, bridge collapse accidents occurred occasionally. Therefore, timely detection of bridge safety hazards through bridge health monitoring is an effective method to avoid bridge safety accidents. The paper expounds the research background, significance and concept of health monitoring system for intelligent health monitoring of bridges. It systematically describes the research status, development process and various components of the bridge health monitoring system at home and abroad. The deficiencies in the current monitoring system are discussed in detail, which provides a useful reference for the future research of health monitoring systems.
