摘要/Abstract

摘要： 块泽河电站大坝为现浇混凝土单曲高拱坝，由于水泥水化热，内部温度上升，在一定约束条件下会产生较大的拉应力，导致混凝土产生裂缝，影响坝体工程质量。对大坝混凝土温度场进行了详细的计算和分析，提出了相应的混凝土温控措施。

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
