水平声学多普勒流速剖面仪在河道流量测验中的运用分析

Application Analysis of Horizontal Acoustic Doppler Velocity Profiler in River Flow Measurement

水平声学多普勒流速剖面仪简称H-ADCP,通常安装在岸壁或桥墩上,其流速测验声束指向水平方向,可使用较小的单元,在较短时间步长内获得精确的流速数据。通过对阜宁(射)水文站H-ADCP代表流速与缆道流速仪法测量的断面平均流速进行比测,分析其在平原水网河道中运用的可行性。

Horizontal Acoustic Doppler Velocity Profiler is abbreviated as H-ADCP.It is usually installed on a quay wall or a bridge pier.Its velocity measurement sound beam points to the horizontal direction.Smaller units can be used to obtain accurate flow rate data in a short time step.By comparing the H-ADCP representative velocity of Funing Hydrological Station with the average velocity of the section measured by the cableway velocity meter method,the feasibility of its application in the plain water network is analyzed.
