摘要
通过采用Midas Civil&FEA软件对某在役双幅部分斜拉桥进行建模计算,根据动静力计算分析结果,确定监测关键截面和测点,并对传感器布设进行优化,对数据传输、预警设置及系统集成进行了整体设计。通过专为大桥健康监测系统开发的智慧监测云网平台统一管理和处理监测数据,形成了一个完整的健康监测系统。然后对系统一年来的运行情况进行了归纳总结,对系统运行中出现的问题进行分析并提出解决方法;对桥梁的部分监测结果(模态和主梁挠度监测数据)分析发现,该健康监测系统达到了设计的预期。
The Midas Civil&FEA software was used to model and calculate a partial cable-stayed Bridge in service.According to the results of dynamic and static calculation and analysis,the key monitoring sections and measuring points were determined,and the sensor layout was optimized.The data transmission,early warning setting and system integration were overall designed.A complete health monitoring system was formed through the unified management and processing of monitoring data by the intelligent monitoring cloud platform developed for the bridge health monitoring system.Then the operation of the system in the past year was summarized,the problems in the system operation were analyzed and the solutions were put forward.Some monitoring results of the bridge including modal and girder deflection monitoring data were analyzed.The analysis results show that the health monitoring system achieves the design expectations.
