摘　　要：本文以红水河乐滩水电站3#号机组和百色水利枢纽RCC坝为背景,介绍了五年来,作者以光纤分布式温度测量系统为手段,研究大坝混凝土结构温度场分布式光纤传感监测的部分成果,包括光纤分布式温度测量系统成果的可靠性和准确性、光纤传感网络和埋设工艺、混凝土水化热的释放过程、冷却水管的作用效果、温度随混凝土浇筑层厚度等的变化规律等。This research is based on the unit No.3 of Letan Hydropower Station on the Hongshui River,and the RCC dam of Baise Water Conservancy Project. The distributed fiber optic sensing system is used to monitor the temperature field in dam concrete structure, and some achievements are presented including the reliability and accuracy of the testing results, the fiber optic sensing network and its embedding technology, the dissipation of concrete hydration heat, the effectiveness of cooling pipes and the temperature varied with the thickness of concrete lift.
