螺旋宏弯光纤应变传感器的结构设计及参数选择

Structural Design and Parameter Selection of the Spiral Macroband Optical Fiber Strain Sensing Technology

光纤传感器自上个世纪问世以来,以其独特的优势在众多领域得到了广泛的应用。针对预应力钢筋混凝土结构关键受力构件-预应力肋的受力状况,对螺旋宏弯光纤应变传感器进行了结构分析和参数研究,为实现大型结构关键受力构件的应力分布测试奠定了基础。

Form the optical fiber sensor appearing last century, it has been widespread used in many fields leaning against its unique dominance. The article has studied the quasi-distributed optical fiber strain sensing technology against the monitoring of the stress of prestressed steel bar, which is the key component of the large-size steel concrete structures. The structural design and parameter selection are studied. It also has served as the foundation for realizing distribute-stress monitoring of the key component of the large-size structures.
