摘要: 钢筋混凝土结构在日常运营中，由于裂缝的出现，会导致内部渗水、钢筋锈蚀等问题，从而破坏结构的安全性。因此，钢筋混凝土结构的裂缝监测是评估建筑结构的重要依据，本文采用分布式光纤应变/温度传感技术(BOTDA)，将传感光缆铺设在混凝土内部和表面，实现了对混凝土裂缝的监测，并且通过钢筋混凝土梁的静载试验，验证了对裂缝宽度跟踪监测的有效性，对结构健康监测有重要意义。
Abstract: In the daily operation of reinforced concrete structures, due to the appearance of cracks, problems such as internal water seepage and steel corrosion will be caused, which will undermine the safety of the structure. Therefore, the monitoring of cracks in concrete structures is an important basis for evaluating building structures. In this paper, distributed optical fiber strain/temperature sensing technology (BOTDA) is used to lay the sensing optical cables on the inside and on the surface of the concrete to realize the occurrence of cracks and cracks in the concrete. Path monitoring and the static load test of reinforced concrete beams verify the effectiveness of the crack width tracking monitoring, which is of great significance to structural health monitoring.
