我们提出了一个真实的火灾测试的结果，使用光纤传感器嵌入混凝土样品。本实验中使用的温度曲线在西班牙/欧洲标准UNE-EN 1363-1温度曲线中进行了描述，该温度曲线用于规范混凝土抵抗真实火灾测试，在火灾室内达到1000°C以上的温度，在混凝土样品内达到600°C。混凝土中已经嵌入了三种类型的光学传感器：光敏锗硼共掺光纤中的标准光纤Bragg光栅；2 .在掺锗光纤中嵌入的再生光纤布拉格光栅（RFGB）；锗硼共掺光纤内嵌RFBG。
We present the results of a real fire test using optical fiber sensors embedded in concrete samples. The temperature curve used in this experiment is described in the Spanish/European standard UNE-EN 1363-1 temperature profile for normalized concrete resistance to real fire tests, reaching temperatures of more than 1000°C inside the fire chamber and up to 600°C inside the concrete samples. Three types of optical sensors have been embedded in concrete: 1. standard fiber Bragg gratings inscribed in photosensitive germanium-boron co-doped fiber, 2. regenerated fiber Bragg grating (RFGB) inscribed in germanium doped fiber, and 3. RFBG inscribed in germanium-boron co-doped fiber.
