SHAPE-SENSING ARRAY BASED ON INVERSE FINITE ELEMENT METHOD AND EXPERIMENT OF BRIDGE DEFLECTION MONITORING

  • 摘要: 桥梁挠度是桥梁工程从设计阶段到运维阶段的重要控制指标,对其进行实时监测对桥梁工程的性能评估至关重要。该文提出一种形状还原传感阵列,该传感阵列基于逆有限元方法,仅通过有限点的实测应变数据即可实时、准确地还原出桥梁挠曲线。详细阐述了逆有限元法基本原理与形状还原传感阵列装置,将该项技术应用于混凝土自锚式悬索桥梁模型进行挠度监测试验研究,分别对桥梁模型进行静态加载与动态加载,通过水准仪与激光位移计对还原得到的挠曲线形状与精度进行验证。结果表明:形状还原传感阵列对于桥梁挠度的监测具有易于安装、数据准确、实时性好的优点,不仅可以准确还原出桥梁挠度,而且可以实时反演出桥梁挠曲线形状,能够有效地评估桥梁工程性能质量。
