摘要:

水文规范中指出水闸淹没堰流通常采用堰闸流量系数法定线推流，但由于水闸堰流时，上下游水位差很小，水位观读误差对流量的精度产生较大影响，无法满足定线精度要求。笔者结合实测流量资料，引入落差指数法率定水位流量关系曲线，精度完全满足规范要求，可在沿江受潮汐影响的大型水闸中推广应用。

Abstract:

It is pointed out by hydrology code that sluice flooded weir flow normally uses weir gate flow coefficient method to determine the line plug flow.But during sluice weir flow, the upstream-downstream water level difference is very small, the water level reading error has great influence on the flow rate accuracy, thus it is unable to meet the requirements of precision alignment.In this paper, the authors combine the measured flow data and introduce the drop index method to determine the water level flow relationship curve.The accuracy meets the standard requirements and can be popularized and appl ied in large sluices along the Yangtze River.
