混凝土结构检测中光纤声发射技术的应用研究

Research on the Application of Optical Fiber Acoustic Emission Technology in the Inspection of Concrete Structures

文中以预应力混凝土梁受弯试验为例,总结光纤传感钢绞线和混凝土梁的制备方式,依照设计要求合理布设测点,对试验结果展开应力损失分析、受弯性能分析以及施工工艺分析,结果显示试验中的预应力光纤传感钢绞线的实用性较好,以期为混凝土结构的检测提供有效参考。

Taking the bending test of prestressed concrete beam as an example,this paper summarizes the preparation method of optical fiber sensing steel strand and concrete beam,reasonably lays out the measurement points according to the design requirements,and carries out stress loss analysis,bending performance analysis and construction process analysis on the test results,and the results show that the practicability of the prestressed optical fiber sensing steel strand in the test is good,in order to provide an effective reference for the detection of concrete structures.
