| 摘 要： | 针对施工期混凝土温度变化规律，采用周期项作为环境气温因子，并累加两个指数函数来考虑水化热温升和通水冷却的影响，构建了施工期混凝土坝温度统计模型。以溪洛渡混凝土坝典型坝段为例，对坝体混凝土温度做了预报。结果表明，该模型可行，预测精度良好。

| Abstract: | In view of variation rules of concrete temperature during construction period, the temperature statistical model of concrete dam is established by taking the periodic item as environment temperature factor and accumulating two exponential functions, which considers the influence of the temperature rise of hydration heat and water cooling system. Taking the typical concrete dam of Xiluodu for an example, the concrete temperature of dam body is predicted. The results show that the proposed model is feasible and the precision of prediction is good. |
