摘　　要：分布式光纤传感技术越来越广泛地应用于火灾报警、电力火灾监控、温度测量、油气井温度监测等方面,近年来在水利水电工程混凝土温度监测、结构变形、渗流、应力应变监测上也在逐步推广和应用。结合拉西瓦水电站工程,利用分布式光纤传感技术实时监测坝体混凝土温度,对监测资料进行了分析并做了比较系统的应用研究。The distributed optical sensing technology has been widely applied in fire alarm, power station fire monitoring, temperature measurement, temperature monitoring of oil and gas wells etc. In recent years, this technology is progressively applied in water and hydropower projects for concrete temperature monitoring, and structure deformation, seepage and strain - stress monitoring. Based on application of distributed fiber optical sensing system for real monitoring of dam concrete temperature in Laxiwa project, the paper presents monitoring data analysis and systematic application research.
