Abstract: The Dam of Kuaizehe Hydro-power Station is single-curved, high arch cast-on place concrete dam. The temperature inside the dam body will raise due to the concrete hydration heat. Under certain constraint condition, the greater expansion stress will occur due to the higher temperature, and this lead to create the crack in concrete, the dam engineering quality will be influenced. In this paper, the dam concrete temperature field was calculated and analyzed in detail, and relevant concrete temperature control measures were proposed.

Key words: temperature field calculation, temperature control, the dam of Kuaizehe Hydro-power Station
