Abstract

Abstract: Taking Chongqing Fuling Shibangou Yangtze River Bridge as an example , the distribution trend analysis on the main beam def1ection monitoring data with different capacities was carried out. And then data rate method was used to identify the distortion data of the def1ection at a single point. The results show that the tested bridge has normal def1ection variation , and the def1ection evaluation time cycle should take 3 months. The data rate method and the analytic hierarchy process method are combined and applied to the evaluation of bridge health monitoring def1ection , which is worthy of further exploration.

Key words: health monitoring, def1ection, evaluation period, distortion data

摘要： 以重庆、清陵石板沟长江大桥为例，对不同容量的主梁挠度监测数据进行分布趋势分析，刀，采用数据变化率法识别出挠度单点失真数据。研究结果表明:该桥的挠度变化幅度正常;挠度评估周期宜取3个月;将数据变化率法与层次分析法结合运用到桥梁健康监测挠度评估中需要进一步探讨。

关键词: 健康监测, 挠度, 评估周期, 失真数据
