摘要
基于连通管原理,采用压力变送器设计了一种大跨径斜拉桥挠度自动监测系统,系统于2013年安装于九江二桥,系统测试的结果与大桥荷载试验中水准仪测量结果比较,两者挠度测量结果的最大相对误差为5%。此外,详细阐述了挠度监测系统的实施方案,为今后该类系统的实施提供了借鉴。
Based on the principle of communicating tubes, a long-span cable-stayed bridge deflection automatic monitoring system is designed by using pressure transmitters. The system was installed in the Jiujiang No. 2 Bridge in 2013. By comparing test results by this system with level measurement results, it shows that the maximum relative error is 5%. In addition, the implement plan of deflection monitoring system is elaborated in this paper, which can provide some reference for implementation of such system.
