摘　　要：堰流和闸孔出流是水库运行调度中泄水建筑物经常出现的两种水流现象:1堰流和闸孔出流的互相转化界限并非一个定值;2堰流和闸孔出流的互相转化还受进口引渠段上游来流条件的影响。结合实际工程,通过模型试验研究,探求一定来流条件下,溢洪道堰流和闸孔出流的互相转化情况,以供类似工程参考。Weir flow and sluice flow are two kinds of water flow,Which often appear in the operation of drainage of building. On the one hand,the value of their mutual transformation is not a constant;On the other hand,the mutual transformation is affected by the condition of coming water flow from upstream in inlet approach channel. Combining the practical engineering and the model test research,we draw a conclusion： under the conditions of specific coming water flow,to explore the circumstance of the mutual transformation of weir flow and sluice flow in spillway to provide the reference for the similar engineering.
