摘要: 混凝土坝中后期通水冷却是一个复杂多因素问题,与通水水温、通水流量和通水时间等相关。基于中后期冷却期间浇筑仓温度动态预测模型,提出了一种中后期通水快速调控方法。先将无热源水管冷却计算式和浇筑仓实测温度相结合预测浇筑仓降温曲线,然后结合中后期冷却的降温速率和目标温度,采用优化算法获得混凝土浇筑仓优化通水方案。实例分析表明,基于无热源水管冷却计算式的浇筑仓温度动态预测模型计算工作量小,混凝土坝中后期通水快速调控方法是可行的,可为混凝土坝中后期通水调控提供及时参考。

Abstract: Pipe cooling for concrete dam in middle-later period is complicated relating with multiple factors including water cooling temperature, water flow and duration. A fast control method for concrete dam in middle-later cooling period is presented based on the dynamic prediction model of concrete pouring surface temperature. In association with the current measured temperature, the curve of temperature decrease is predicted based on calculation formula of pipe cooling without heat resource. Then the optimal pipe cooling scheme is obtained by adopting optimization algorithm according to temperature cooling rate and target temperature in middle-later period. Case study shows that the prediction model based on calculation formula of pipe cooling without heat resource has small workload, and the fast control of concrete dam in middle-later cooling period is feasible.

Key words: middle-later cooling, fast control, concrete dam, pipe cooling measures
