结构健康评估与预警系统在崇启大桥中的应用

摘要

In the process of setting health monitoring system of Chongqi bridge,the structural health assessment and early warning system are compiled according to the structural characteristic of Chongqi bridge. Scoring method of the system is directly relevant to warning levels and,therefore,is able to reduce manual intervention in calculations considerablely. The scoring results of monitoring items indicate that the measured data are in mormal level and the measured structural unit are in safe state, and the proposed system can reflect safe performance of Chongqi bridge effectively.%针对崇启大桥结构特点编制了结构健康评估与预警系统，其评分方法与预警水平直接相关，显著减少了评估计算中的人工干预。对各监测量进行评分计算，结果表明：各监测量处于实测数据的正常水平，各监测部位均处于安全状态下，证明崇启大桥结构健康评估与预警系统能够有效监测大桥安全状况。
