桥梁健康监测及传感器的优化布置

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。

Health Monitoring of Bridges and Optimal Placement of Sensor

In order to avoid or reduce certain damages and failures to bridge during the service period, it is necessary to take effective monitoring method for the bridges. The necessity of health monitoring of bridges are introduced in this paper. Then the development and investigation of health monitoring of bridges in recent years are presented. The researches on the optimal placement of sensor are emphasized, and some examples are listed. Finally the problems which need to further study are pointed out in the paper.
