【摘要】：为解决桥梁结构健康监测系统不易对早期损伤识别的问题,首先阐述了基于健康监测的损伤预后和安全预后的基本概念,讨论了损伤预后和安全预后的基本理论框架,包括监测系统、物理模型及预后模型3个部分;其次综述了基于模型预后技术、数据驱动预后技术等的研究进展及应用,最后提出了基于健康监测的桥梁结构损伤预后和安全预后面临的挑战。综合分析表明:基于知识发现、神经网络、统计分析、物理模型及其混合系统等是潜在的有效解决方法;基于多元混合的预后方法将是未来预后技术的主要发展方向之一,损伤及安全预后技术将是克服健康监测技术瓶颈的有效方法之一,可供桥梁结构健康监测、运营养护和维修加固参考。
[Abstract]:In order to solve the problem that the bridge structure health monitoring system is not easy to identify the early damage, the basic concepts of injury prognosis and safe prognosis based on health monitoring are expounded, and the basic theoretical framework of injury prognosis and safe prognosis is discussed. It includes three parts: monitoring system, physical model and prognosis model. Secondly, the research progress and application of model-based prognostic technology, data-driven prognostic technology and so on are reviewed. Finally, the challenges of bridge damage prognosis and safe prognosis based on health monitoring are put forward. The comprehensive analysis shows that knowledge discovery, neural network, statistical analysis, physical model and hybrid system are potential effective solutions. The prognosis method based on multivariate mixing will be one of the main developing directions of the future prognostic technology. The injury and safe prognosis technique will be one of the effective methods to overcome the bottleneck of health monitoring technology, which can be used for bridge structure health monitoring.
