走航式ADCP在阿勒泰水文站测流中的应用分析

Application Analysis of Walking ADCP in Flow Measurement of AltayHydrological Station

结合传统流速仪测定方法对比走航式ADCP在阿勒泰地区水文测流的适用性,结果表明:由于阿勒泰山区河流较多,高水流速较大,使得走航式ADCP适用性降低,但在畅流期中低水时,流速较小时,具有一定的适用性,在中低水流速时,通过流量测定精度分析,走航式ADCP流量测定的系统误差和随机不确定度均可满足河流流量测验规范的允许误差要求。研究成果对于阿勒泰地区河流巡测方案的制定具有参考价值。

Combined with the traditional method of measuring the flow velocity,the applicability of the walking ADCP in the hydrological measurement of the Altay region is studied.The results show that due to the large number of rivers in the Altay mountains and the high water velocity,the applicability of the walking ADCP is reduced.During the low and medium water flow period,when the flow rate is small,it has certain applicability.At the low and medium water flow rate,the system error and random uncertainty of the ADCP flow measurement through the flow measurement accuracy analysis can meet the river flow test normative tolerance requirements.The research results are of reference value for the development of river survey plan in Altay region.
