摘要
文章基于影响线的荷载识别方法和北澄子河大桥健康监测系统的长标距FBG传感器实测数据,提出了3跨连续梁桥的荷载识别方法。试验数据分析表明,该方法能够较精确地识别单车移动荷载作用下的车辆速度和车重,车速识别误差可控制在10%以内,车重识别误差可控制在15%以内。
In this paper, the load identification method for a three-span continuous beam bridge was proposed based on the influence line theory. This method was studied and confirmed through the moving load experiments on the Beichengzi River bridge. The results of the SHM data showed that the relative error of speed could be controlled within ± 10%, and that the relative error of load identification could be controlled within ±15%.
