A New Numerical Model for High Concrete Dam Cooling by Water Flowing and Application

New methods for high concrete dam cooling by water flowing were introduced in this article. The heat-fluid coupling model, which can better simulate disposition of cooling pipe and water temperature rise along the flow, will bring more accurate simulation results of temperature field. The nonlinear creep model can better reflect the nonlinear relation between concrete creep and stress ratio of concrete. The temperature space-time dynamic control method, improving from the traditional multi-stages water cooling method, can optimize the process of temperature drop and thus decrease the thermal stress. And the computation results of high concrete dams (Guandi, Wanjiakouzi and Jinping-1 in China) show that the temperature by numerical are lit the actual monitor values. New methods of temperature simulation presented in this paper for high concrete dam will have good application prospect in practical project.
