Abstract: A great cleal of distributed optical fibers were embedded at Guangzhao hydropower station. Basing on understanding of the concrete temperature measured by distributed optical fibers, the mathematical statistics software SPSS was applied to process the temperature data with variance analysis and relevant analysis. The analysis result indicated that the data of concrete temperature measured by distributed optical fiber was real and reliable, worthy popularization.

摘要： 在北盘江光照电站内铺设了大量的分布式测温光纤。基于对光照电站分布式光纤测温系统测得大坝混凝土温度数据的掌握和了解, 文章应用数学统计软件SPSS 对分布式光纤实测大坝混凝土温度监控数据进行了方差分析和相关性分析, 同时结合混凝土温度与其散热条件间的关系对测温数据进行分析。分析结果表明, 分布式光纤实测大坝混凝土温度真实、可靠,有较高的推广应用价值。
