摘　　要：对影响坝体混凝土温度的参数采用双曲线公式和指数公式进行了仿真分析,包括混凝土与绝热温升的关系、临空面和非临空面温度点过程线和一期冷却措施对最高温度的影响,为设计单位提供了制定温控方案的依据。In this paper the hyperbolic formula and index formula are adopted to simulate and analyse the parameters affecting dam body concrete temperature,including the relationship between the concrete and the adiabatic temperature rise,exposed surface and non-exposed face temperature points temperature variation process lines and influence of the first stage cooling measures on the maximum temperature rise.All these provide the temperature control scheme basis for the design organizations.
