| 摘 要： | 文章根据光纤传感器的基本原理,阐述选用两根竖向预应力粗钢筋,分别在其表面粘贴片式光纤光栅传感器和裸光纤光栅传感器,同时用普通电测系统监测预应力筋中的张拉应力进行试验。试验发现,这两种光纤光栅传感器波长移动量同应力应变具有良好的线性关系,可应用于工程实际。

| Abstract: | According to the basic principle of fiber sensor,two vertical pre-stress rebar were selected and attached SMD fiber bragg grating sensor and regular fiber bragg grating sen-sor respectively.They are then tested by regular electronic measurement system.The test result shows that the wavelength movement these two types of fiber bragg grating sensors has great linear relationship with stress strain,thus these sensors can be used in real con-struction practice. |
