本文将光纤传感器埋入混凝土结构中,供定时检测结构的应力、应变、裂缝发展等内部状态参数的变化,并也分析和讨论了光纤传感器埋入混凝土结构的方法及原理。同时对埋入光纤传感器的混凝土棱柱构件作了实验研究。实验结果表明,光纤传感器的输出变化能反映结构内部应变及裂缝等状态的变化情况。
In this paper, the optical fiber sensor embedded in concrete structures for the regular detection of structural stress, strain, crack development and other internal state parameters change, and also analyzed and discussed the optical fiber sensor embedded in the concrete structure of the method and principle. At the same time, the embedded experimental research on the concrete prism member of optical fiber sensor. The experimental results show that the change of the output of the optical fiber sensor can reflect the changes of the internal strain and crack in the structure.
