摘　　要：平乐水文(三)站天然测验河段因下游水电站改变为库区回水河段后,使测验断面水位流量关系发生了变化,常规流量测验受到严重影响。为确保测报安全,提高信息采集自动化和测报能力,在平乐(三)水文站开展水平式ADCP与断面平均流速(走航式ADCP)进行同步比测率定分析,结果表明水平式ADCP测流精度符合规范要求,在线测量数据满足现实使用要求。The natural measuring river section of Pingle III Hydrological Station had changed into river section affect⁃ed by reservoir backwater due to the construction of a downstream hydropower station,which led to the change of water level-flow relationship of measuring profile,and the conventional measurement was seriously affected.In or⁃der to ensure measuring and reporting security,improve the automation level of information acquisition and the mea⁃suring/reporting capability,synchronous comparative measurement and calibration analysis were conducted be⁃tween horizontal ADCP and navigational ADCP used for measuring cross-sectional average flow velocity at Pingle III Hydrological Station.The results demonstrate the flow measuring accuracy of horizontal ADCP conforms to the specification,with the on-line measured data meeting the requirements of practical use.
