摘  要：ADCP在长江中高水流量采用底跟踪模式施测存在偏小现象，为检验国产RIV ADCP性能及软件功能是否满足流量测验规范要求，开展对RIV ADCP适应性和精度测试。在长江下游流量70 342 m³/s下，通过与用于流量基本资料收集的同频率进口RDI ADCP进行特征值及功能测试 。测试发现，比测的流量、面积、流速等各项指标与进口RDI ADCP的精度和功能基本一致，满足规范的精度要求。国产RIV ADCP可替代进口设备用于流量基本资料收集，但软件输出功能还需进一步完善。

Abstract: the middle and high water flow of the Yangtze river measured by the bottom tracking mode using ADCP is relatively smaller than real. In order to test if the performance and software functions of domestic RIV ADCP meet the requirements of flow test specifications, the adaptability and accuracy of RIV ADCP is tested. Under the flow of 70 342 m³/s in the lower reaches of the Yangtze River, the eigenvalues and software functions of RDI ADCP imported at the same frequency as those used for collecting basic flow data are tested. The test results show that the accuracy and function of the flow, area and flow rate are basically same as those of the imported RDI ADCP, which meets the accuracy requirements of the specification. The precision of RIV ADCP made in China can replace imported equipment for collecting basic flow data, but the function of software output needs to be further improved.
