中文摘要：

冰塞或冰盖下输冰受热力、水力以及边界条件等影响,计算河道在稳封期的冰流量对计算冰塞厚度及冰期水位具有重要的意义。根据对实验室试验数据的分析,提出平衡输冰形式的回归公式。同时对比了黄河河曲段稳封期的实测资料,结果显示这一计算输冰量公式的结构形式是合理的,可为天然河道稳封期输冰流量计算提供参考。

英文摘要：

Ice discharge under ice jam or ice cover is the result from the combined effects of the thermal, hydraulic and boundary conditions. Based on the analysis of the experimental data, the formula for calculating ice discharge is proposed. Meanwhile, compared with the data of stability freezing period from Hequ region in the Yellow River, the result shows that the proposed form of formula is rational and can offer reference to the calculation of ice discharge in the during freeze-up.
