摘要
桥梁在交通网络中充当着极其重要的角色,其正常运行与否关系到人民生活幸福指数的高低。所以,为其建立结构健康监测系统以实时监测其安全状态、预警其异常行为及预测其工作性能走向的方法极为必要。桥梁结构传感器的优化布置,简单来说就是通过正确合理地布置所需传感器来获取桥梁的各项信息。传感器的优化布置研究的关键则在于其布置方法与评价准则,国内外的学者经过多年的研究,在该领域取得一定的突破与创新,但是仍然存在很多不完善的地方,如何通过改进各种算法来确定传感器优化布置最优解成为研究的主要方向。该文重点阐述传感器优化布置准则和传感器优化布置的方法在目前研究方向中发挥的重要作用,并对桥梁健康监测的后续发展表达看法和展望。
Bridge plays an extremely important role in the traffic network,and its normal operation is related to the happiness index of people's life.Therefore,it is very necessary to establish a structural health monitoring system to monitor its safety status,warn its abnormal behavior and predict its performance trend in real time.To put it simply,the optimal arrangement of sensors in bridge structure is to obtain all the information of the bridge by arranging the required sensors correctly and reasonably.The key to the research on the optimal layout of sensors lies in its layout methods and evaluation criteria.After years of research,scholars at home and abroad have made some breakthroughs and innovations in this field,but there are still many imperfections.How to improve various algorithms to determine the optimal solution of sensor layout has become the main research direction.This paper focuses on the important role of sensor optimal layout criteria and methods in the current research direction,and expresses its own views and prospects for the follow-up development of bridge health monitoring.
