摘　　要：梧州水文站上游约2000 m是干流浔江与支流桂江交汇处,下游170 m为云龙大桥,水流形态复杂,实现流量在线监测是一大难题。尝试基于回波强度判断H-ADCP单元流速的有效性,通过建立双探头H-ADCP不同单元流速组合计算的指标流量与断面流量模型及水量计算分析来研究双探头H-ADCP在线流量监测系统在西江黄金水道梧州水文站河段的适用性。结果表明,水位在3.29~22.31 m,指标流量在3270~39500 m^(3)/s时双探头H-ADCP在线流量监测系统可在梧州水文站应用。The intersection of the mainstream Xunjiang River and the tributaries Guijiang River is about 2000m in the upstream of Wuzhou Hydrological Station.Yunlong Bridge is in the downstream of Wuzhou Hydrological Station of 170 m.The flow pattern is complex.It is a difficult problem to realize online flow monitoring.Try to judge the effectiveness of HGADCP unit flow rate based on echo intensity,and establish different unit flow rate groups of double probe HGADCP.Combined with the calculated index flow and section flow model and water volume calculation and analysis,the double probe HGADCP online flow monitoring system is studied in Wuzhou hydrology of Xijiang golden waterway.The results show that the dual probe H-ADCP online flow monitoring system can be applied in Wuzhou Hydrological Station when the water level is 3.29~22.31m and the index flow is 3270~39500 m^(3)/s.
