Abstract: Baihetan hydropower dam is a concrete double-curvature arch dam. During the dam construction, some temperature control measures are needed all the year round, and the cost of temperature control measures is high. For reflecting the inner constitution of the temperature control cost, this paper first analyzed the process of temperature control construction and broke down the temperature control cost. Then, based on the staffing at the construction site, the material  onsumption and the equipment layout, the unit-price of the concrete pre-cooling and water cooling were calculated by the material measuring method.

Key words: Baihetan hydropower station, double-curvature arch dam, temperature control cost, unitprice of the concrete pre-cooling and water cooling, material measuring method

摘要： 白鹤滩水电站拦河坝为混凝土双曲拱坝，大坝全年温控施工，温控费用高。通过对施工期温控过程进行分析，分解温控费用，并根据施工现场人员配置、材料消耗、设备布置，采用实物量法对关键性的混凝土预冷和通水冷却单价进行分析计算。
