Abstract
To ensure the safety of a dam it is capital to monitor it, which can be done through visual inspection or analysis of the measurements collected through the monitoring instrumentation system. In Roller-Compacted-Concrete dams, the instrumentation system focuses on displacements and water pressure over thermal monitoring of the structure. Important data, such as water’s temperature and downstream face temperature, are not gathered during the life of the dam. Whereas identifying the thermal field within the dam is crucial to understand its structural behavior. This paper shows the major effect of the dam’s temperature over its displacements using a statistic model. Then, a method to develop an accurate thermal model of Roller-Compacted-Concrete dams using the software Cast3M and based on different hypothesis is explained. The results of the computation will be compared with the available monitoring measurements to verify the accuracy of the simulation and its representativeness of the effective thermal field within the structure.
