H-ADCP在受水利工程影响河道流量监测的应用研究

Application of H-ADCP in Monitoring of River Flow Affected by Hydraulic Engineering

为提高受水利工程影响测验断面推流精度,提升H-ADCP流量在线监测系统水平,以梅铺水文站为例,探讨H-ADCP在受回水顶托及上下游电站调蓄综合影响下,通过一元三点插值法建立代表流速相关关系曲线以及最小二乘法建立的多元回归模型的可行性,以及不同方式推求流量的精度和过程差异。

In order to improve the flow pushing accuracy of test section affected by hydraulic engineering and improve the level of H-ADCP flow online monitoring system,taking Meipu Hydrological Station as an example,the feasibility of establishing a representative velocity correlation curve and a multiple regression model established by the least square method through the one-yuan three-point interpolation method under the comprehensive influence of backwater top support and upstream and downstream power stations was discussed.The accuracy and process difference of flow rate estimation by different methods are also discussed.
