Abstract :
In this research, to profile the temperature field of a concrete foundation in Qinshan nuclear power station, the thermal properties of concrete were analyzed using ANSYS. This research provides a numerical method to identify the thermodynamic parameters of concrete, such as the specific heat, conductivity, coefficient of surface heat and rate of hydration, with the target optimization principle. The simulation results of the temperature field fit well with the data collected from Qinshan nuclear power station, which means that this method is valuable in charactering the development of temperature filed in mass concrete structure.
