红山窑节制闸改建后淹没式孔流水位流量关系单值化分析
|
Abstract:
为了推求红山窑闸淹没式孔流这一主要流态下的水位流量关系，选取2012~2019年实测淹没式孔流流量资料，利用堰闸流量系数法和堰闸过水平均流速法两种方法分别进行分析计算。结果表明，两种方法率定出的水位流量关系均符合《水文资料整编规范》要求，可以用于水文资料整编。本文对条件类似的水文站率定堰闸水位流量关系有一定的参考价值。
To identify the stage-discharge relation of reconstructed Hongshanyao Sluice under its main flow regime, i.e., the submerged sluice flow, the measured discharge data of submerged sluice flow from 2012 to 2019 were collected and used to calibrate the stage-discharge relationship by the weir sluice discharge coefficient method and the average horizontal flow velocity passing through sluice method, respectively. The results show that the stage-discharge relationship obtained by the two methods are in line with the requirements of the Code for Hydrologic Data Compilation, and can be used for hydrologic data compilation. This paper is valuable to an extent for the hydrological stations with similar conditions to identify their stage-discharge relation.
