摘要
针对冰期明渠输水中冰情问题,通过合理地选取计算单元;分析与冰期明渠输水中冰情有关的地理位置、气象因素、渠道水力学、水热力学等相关参数的计算方法;运用热平衡原理建立了冰情预报模型;对模型中相关参数的计算,实现对冰期明渠输水中的冰情预报。
Based on the problem of ice state in open canal with delivered water, the location and weather condition of the open canal are analyzed. At the same time, the calculating method is determined. Meanwhile, a model of forecasting ice state is established by using the theory of thermal balance, then the ice state can be forecast on the basis of calculation with the model according to the parameter concerned.
