导流底孔回填混凝土水泥含量高，温控难度大，一般需要埋设冷却水管进行通水冷却。针对导流底孔回填混凝土的特点，从动态预测角度出发，将有热源水管冷却计算式结合混凝土浇筑仓实测温度，根据浇筑仓当前实测温度动态更新有热源水管冷却计算式中的 Ti ，然后进行未来 n 天混凝土浇筑仓温度动态预测，以指导和调控现场通水措施。向家坝导流底孔回填混凝土温度动态预测的实例分析表明，建议的温度动态预测式是可行的。

The concrete plugging of bottom diversion outlet has high proportion of cement,posing big challenge to the temperature control,therefore pipe cooling is needed.In this research,we recommend to combine the heat pipe cooling calculation formula with the measured temperature of concrete block,which means to dynamically update Ti in the heat pipe cooling calculation formula according to the measured temperature,and then predict the dynamic temperature of concrete block of n days in the future to guide and control the pipe cooling.The dynamic prediction for concrete temperature is proved to be feasible by the practical example of concrete temperature of plugging of bot-tom diversion outlet at Xiangjiaba Hydropower Project.
