摘要
针对长期服役的土木工程结构因负载、结构老化、自然灾害等造成的结构损伤带来的安全隐患,建立了基于B/S的桥梁结构健康监测、安全预测平台,在线监测影响桥梁结构健康的主要参数,对异常参数信号进行报警处理,并对历史数据走势采取多项式、对数、线性及指数等4种回归预测方法进行趋势预测,以判断桥梁结构损伤走势。从系统设计方面,详细介绍了系统功能模块和软件架构,并结合Silverlight强大的界面表现能力实现了具有丰富体验的界面效果,增强了软件的友好性和交互性。
B/S-based health monitoring and safety prediction platform of bridge structure is established in consideration of potential safety hazard caused by load and structure aging of civil engineering after service for a long period and natural disaster. The platform can realize on-line monitoring of major parameters affecting bridge structure health and send alarm signal for abnormal parameter. Tendency of historical data are predicted by using four regression prediction methods, including polynomial, logarithm, linearity, exponential and power, to judge the damage tendency of bridge structure. On the aspect of system design, functional module and software configuration are introduced in details, and powerful interface expression capacity of Silverlight software is used to realize interface effect providing abundant experiences and to increase user-friendly and interactive functions.
