| 摘 要： | 介绍了应用定点式横向声学多普勒流速仪进行实时流量在线监测方面的比测率定研究工作。主要从设备选型、安装位置、代表流速计算、单元流速区间选择、关系率定、精度评定、测点流速分析等方面进行了分析研究。通过设备选型、安装位置、单元流速区间选择等多方面的比较分析,选择最佳方案,进行比测分析,率定出代表流速与断面平均流速的关系。重点对设备安装位置、单元流速区间的选择、流速横向分布等进行比较分析,对于其他测站的类似H-ADCP监测方案有一定的指导意义。

| Abstract: | This paper introduced the comparative gauging calibration research work of real-time flow on-line monitoring by using fixed-point type and lateral acoustic Doppler current meter,and analyzed the equipment selection,installation location,representative velocity calculation,unit velocity interval selection,relationship calibration,accuracy evaluation and velocity analysis of measuring points.The best scheme was selected through the comparison analysis of the above aspects,and the relationship between representative velocity and section average velocity was also determined.The comparison and analysis of the installation location of equipment,the selection of unit velocity interval,and the lateral distribution of velocity are of guiding significance for the similar H-ADCP monitoring schemes of other stations. |
