摘要
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。
An approach by using Embedded fiberoptic sensors real-time detecting internal state parameters, such as stress, strain, growth of crack of concrete structure, was postponed in this paper. The embedded method and principle for fiberoptic sensors was discussed, and the experimental study of concrete prismoid member, which was embedded fiberoptic sensors, was given. The initial experimental results show that the embedded fiberoptic sensor offers the possibility of detecting the internal state such as change of internal strain, strss, and crack growth of concrete structure, and also.
