基于健康监测数据的桁架拱桥安全性评定研究

Study on Safety Assessment of Truss Arch Bridge Based on Health Monitoring Data

桁架拱桥由于其结构特点导致其运营过程中出现诸多病害,严重影响了其安全性。因此,对桁架拱桥进行安全性评估显得尤为重要。本文以健康监测系统采集的数据为研究对象,对基于健康监测数据关联性的结构损伤识别方法进行了研究,并进行了实例计算,结果显示基于健康监测数据关联性的结构损伤识别方法可以有效地判断结构的损伤。同时,本文还利用健康监测数据对基于可靠度分析的桁架拱桥安全性评定方法进行了探讨,结果显示,该方法切实可行、准确有效。

Because of the structural characteristics of Truss Arch Bridge,many diseases appear in the course of its operation,it is seriously affects the security of the bridge.Therefore,it is very important to evaluate the safety of Truss Arch Bridge.Taking the data collected by health monitoring system as the research object,this paper studies the method of structural damage identification based on the correlation of Health Monitoring Data,and carries on the example calculation,the results show that the structural damage identification method based on the correlation of health monitoring data can effectively identify the structural damage.At the same time,this paper also discusses the method of Safety Assessment of Truss Arch Bridge based on reliability analysis by using health monitoring data.
