Abstract EN
The thermal boundary conditions in the construction and operation phases of a concrete arch dam are always complex.
After sealing, differences between the arch dam temperature and its sealing temperature can cause compressive or tensile stresses.
Based on measured temperature of an arch dam located in China, a temperature rise phenomenon (TRP) is found in the after-sealed regions of the arch dam.
By mining and analyzing the temperature data of various monitoring apparatus embedded in the arch dam, higher environment temperature is considered to be the main cause for the occurrence of the TRP.
Mathematical methods for complex thermal boundary conditions, including external boundary conditions and internal heat source conditions, are proposed in this paper.
A finite element model is implemented with the concern of the construction phase and operation phase of the arch dam.
Results confirm good agreement with the measured temperature and verify the conjecture that the TRP occurs mainly because the external temperature of the arch dam is higher than its sealing temperature.
