本文结合风陵渡黄河大桥长期健康监测,介绍应力监测数据的分析处理,提出一种新的分析方法,并详细分析了该方法的特点,该方法可识别出车辆荷载产生的应变及总体应变趋势,并对应变趋势进行回归分析,从而为健康监测系统预警阀值的确定提供参考。 Based on the long-term health monitoring of Fenglingdu Yellow River Bridge, this paper introduces the analysis and processing of stress monitoring data, proposes a new analysis method and analyzes the characteristics of this method in detail. This method can identify the strain caused by vehicle load and the overall strain trend , And regression analysis of strain trends, so as to provide a reference for the determination of warning threshold of health monitoring system.
