自锚式悬索桥监测数据分析

Data Analysis of Self-Anchored Suspension Bridge Monitoring

为保证桥梁在设计使用寿命内的安全运营,某自锚式悬索桥安装了健康监测系统,在监测期间内,利用数据清洗技术,剔除异常数据后,结果表明主梁位移未达到满载设计值,主梁位移状态正常;现场索力增量平均值均未超过预警值,吊索工作状态正常;倾角监测数据正常,风速风向、温湿度环境监测类数据正常,桥梁目前主体受力处于合理范围之内,桥梁运行安全。

In order to ensure the safe operation of the bridge during the design service life,a self-anchored suspension bridge was installed with a health monitoring system,and during the monitoring period,after using data cleaning technology to remove abnormal data,the results showed that the main girder displacement did not reach the full load design value,and the main girder displacement state was normal.The average value of the cable increment on site did not exceed the early warning value,and the working state of the sling was normal;The inclination monitoring data is normal,the wind speed and direction,temperature and humidity environment monitoring data are normal,the current main force ofthebridge is within a reasonablerange,and the bridge operation is safe.
