走航式ADCP测流精度控制措施研究

Research on control measures of flow measurement accuracyof navigational ADCP

走航式ADCP已经广泛应用于河道流量测量,但是存在无处鉴定,参数设置不合理,施测不规范等问题,无法保证测验精度要求。为了提高走航式ADCP测流精度,提出了ADCP选型合理,安装要求严格,参数设置合理,测验方法正确及施测过程规范等控制要求和措施,为正确应用走航式ADCP提供了重要参考。

Navigational ADCP has been widely used in river flow measurement,but there are some problems such as nowhere to identify,unreasonable parameter setting and irregular measurement,which cannot guarantee the test accuracy requirements.In order to improve the accuracy of ADCP flow measurement,some control requirements and measures were put forward,such as reasonable ADCP type selection,strict installation requirements,reasonable parameter setting,correct dynamic bottom test method,and specification of test process,which could provide important reference for the correct application of ADCP.
