手持电波流速仪在黄山地区中高水流量测验中的应用研究

Study on the application of hand-held radio wave flowmeter inmiddle and high water flow measurement in Huangshan area

手持电波流速仪是解决黄山地区中高水测验难题的有效方法,为使手持电波流速仪测验成果科学合理,本文对黄山地区祁门、新亭和休宁水文站中高水手持电波测流数据与缆道流速仪、ADCP测流成果进行分析比较,研究了相同断面条件下不同电波流速仪,以及同一部电波流速仪用于不同断面情况下的应用情况。经研究推断手持电波流速仪比测系数在不同的测验断面、不同仪器、不同水位情况下均是有差异的,同一断面应尽量固定使用同一型号电波流速仪并建立水位级与比测系数关系曲线。而不同断面、不同电波流速仪应单独建立相关比测系数以供推流选用。

Handheld radio wave current meter is an effective method to solve the problem of medium and high water test in Huangshan area.In order to make the test results of handheld radio wave current meter scientific and reasonable,this paper analyzes and compares the data of medium and high water wave current measurement in Qimen,Xinting and Xiuning hydrological stations in Huangshan area with the results of cableway current meter and ADCP current measurement,and studies the application of different radio wave current meters under the same cross-section conditions and the same radio wave current meter in different cross-sections.Through research,it is inferred that the comparison coefficient of hand-held radio wave current meter is different in different test sections,different instruments and different water levels.The same type of radio wave current meter should be used as fixed as possible in the same section and the relationship curve between water level and comparison coefficient should be established.However,different cross-sections and different electric wave current meters should separately establish the correlation comparison coefficient for the push flow selection.
