为了避免或减小桥梁在运营期间由于各种原因出现损伤破坏 ,必须对桥梁结构采取有效的监测。本文对桥梁工程健康监测的必要性进行了阐述 ,并介绍了目前桥梁健康监测的发展和研究现状 ,重点讨论了传感器优化布置的研究 ,还引用了部分实例进行说明 ,最后指出了还需进一步研究的问题。 In order to avoid or reduce the damage of the bridge due to various reasons during operation, the bridge structure must be effectively monitored. This paper describes the necessity of bridge health monitoring and introduces the current development and research status of bridge health monitoring, focusing on the study of the sensor placement optimization, but also cites some examples to illustrate, and finally points out the need for further study The problem.
