摘　　要：以往ADCP进行河道断面流量测验的应用方式是走航式,多沙河流存在"动底",影响底跟踪应用并给流量测验结果带来较大误差。采用多线积深式流量测验方法,利用ADCP依次对多条垂线进行流速流向、水深测量,测记起点距计算总流量,并在黄河中游吴堡、府谷两站开展了与流速仪法的流量比测试验,对资料进行了分析和评价,说明多线积深式流量测验方法作为低沙、平水期流量测验的一种应用方式,可缩短历时,提高测报技术水平,具有较好的应用前景。Formerly,the method that ADCP uses to measure the flow of fluvial cross section is measuring while sailing,and there exists flowing ground in heavily silt-carrying rivers,which can lead to a great error in flow measurements. Now,ADCP measures the rate,depth and quantity of flow using the multi-line method. This study conducted a lot of contrast experiments in Wubu Hydrological Station and Fugu Hydrological Station,and the results show that this method can help to reduce the measuring time and raise the measuring level,which has a great application prospect.
