Abstract: Site test for 3 m concrete pouring deck with 2-layer water cooling pipes was carried out based on distributed fiber temperature measuring system. The spatial resolution of temperature measuring system was set as 0.5 m and the sample interval was 0.15 m. The test result showed that the temperature measuring system of distributed fiber was of good effect and it can identify the location of the 2-layer water cooling pipes in the 3 m concrete pouring deck. However, it cannot properly reflect its vertical temperature distribution. Therefore, temperature measuring system of distributed fiber was applicable to the temperature measurement in gentle variation direction.

摘要： 基于分布式光纤测温系统对布置两层冷却水管的3 m厚混凝土浇筑仓垂直向温度分布进行了现场试验。分布式光纤测温系统的空间分辨率设置为0.5 m，采样间隔设置为0.15 m。试验表明，分布式光纤测温系统测温效果良好，可以捕捉到3 m厚混凝土浇筑仓的两层冷却水管的位置，但难以合理反映3 m厚浇筑仓的垂直向温度分布，分布式光纤测温系统适用于温度变化比较平缓方向的温度监测。
