摘　　要：桥梁的安全运营,是关系到国计民生的大事.因此,桥梁结构健康监测系统正成为国内外学术界和工程界的研究热点.无线传感器网络由于安装方便、维护成本低和部署灵活等特点,已被广泛应用于桥梁健康监测系统中.对现有的基于无线传感器网络的桥梁健康监测系统进行综述,依次介绍了各个子系统中的基本原理和典型方法,并结合多个具体实例分析了系统中的关键技术,最后总结了已有系统中存在的问题和未来的研究方向.Bridge operation safety is critical to national security and people＇s livelihood. The structural health monitoring of bridges has emerged as an increasingly active research area. Wireless sensor networks （WSNs） technology is known to be easy to deploy and inexpensive to maintain. It is thus suitable for structural health monitoring of bridges. This paper gives a survey on structural health monitoring systems based on WSNs technology. Some basic theories and typical methods in subsystems are presented, and critical technologies are analyzed. At the end, varies issues in existing systems and directions on future work are analyzed and summarized..
