摘要：

Optical fibers were embedded in a large concrete dam during construction for real-time temperature measurements to enable reconstruction of the three-dimensional temperature distribution in the Baihetan dam. A three-dimensional temperature analysis was developed to manage the fiber optic measurements and predict the construction quality through real-time data acquisition, analysis and processing of the massive temperature data sets to monitor the temperature changes. The results show that the system provides efficient analyses of the massive amounts of temperature data and accurately analyzes the temperature distribution characteristics in concrete dams. This system can be directly applied for temperature monitoring and analysis of other concrete dam projects. The system can also be extended to the management and analysis of massive data sets for other projects. © 2021, Tsinghua University Press. All right reserved.
