摘　　要：桥梁作为生命线工程的重要组成部分,在国民生活、国家安全和经济发展等各个方面发挥着及其重要的作用。随着高速铁路的不断发展,桥梁健康监测技术的研究和应用迫在眉睫。本文分析了桥梁健康监测的需求,设计了桥梁健康监测系统,并研究了超声波、连通液位、振弦、光纤光栅等传感器技术,探讨了桥梁健康监测需考虑的监测点布置、时间同步、数据管理等问题。通过实验分析,验证了桥梁健康监测系统的有效性,为实现生命线工程中的桥梁健康监测提供了可行的技术方案。As a key part of the lifeline engineering, bridges play an extremely important role in many aspects. With the development of the high-speed railway, the research of bridge health monitoring technology becomes urgent. The bridge health monitoring requirements are analyzed and the bridge health monitoring system is designed. Sensor technologies, such as ultrasound, connected fluid level, vibrating string, fiber bragg grating are studied. Also, several problems including arrangement of monitoring points, time synchronization, data management are discussed. The experiment result shows that the bridge health monitoring system presented is feasible.
