吉首站水平ADCP测验方法应用研究

Application Research on Measurement methods of Horizontal ADCP in Jishou Hydrological Stations

针对湖南吉首站水流条件复杂的实际情况,对水平ADCP的合理安装、流量计算可靠性和流速回归方程优化等进行了探讨,分析了影响水平ADCP测速的主要因素,通过吉首站两种测流方法定线整编精度对比,说明了吉首站3年来使用ADCP测流的精度较高,最后提出了需要进一步研究的主要问题。

According to complicated flow condition of Jishou hydrological station in Hunan province, reasonable installation, discharge calculation reliability and velocity regression equation optimization for horizontal ADCP are discussed. Main factors that can influence horizontal ADCP velocity measurement are analyzed. By accuracy comparison for determination of stage-discharge curve between two flow measurement methods, it has proved that three-year＇ s application of ADCP in Jishou hydrological station has higher flow measurement precision performance. Finally, main issues that should be further studied are put forward.
