| Abstract: | 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. |
