    摘要:

    在分析现有水文站流量在线监测实现途径的基础上,综述了流量在线监测中流速面积法和水力学法的最新研究进展。依据通过局部流速计算断面流量原理的不同,将基于流速面积法的水文站流量在线监测方法分为指标流速法、流速分布模型法和表面流速法3类。并对比分析H-ADCP法、V-ADCP法、二线能坡法、雷达法、粒子图像法、量水建筑物法及水工建筑物法的优缺点,指出在提高在线监测精度、改善稳定性和促进应用3方面应进行进一步深入的研究。

    Abstract:

    Based on the analysis of the existing methods of on-line discharge monitoring of hydrometry stations, this paper summarizes the latest research progress of velocity-area method and hydraulic method in on-line discharge monitoring. Cross section discharge was calculated based on local flow velocity, and the on-line discharge monitoring method based on velocity-area method is divided into three categories: index-velocity method, velocity distribution model method and surface velocity method. This paper analyzes the advantages and disadvantages of H-ADCP method, V-ADCP method, two-line energy slope method, radar method, particle image method, water measuring building method and hydraulic building method, and points out that further research will be carried out in improving online discharge monitoring accuracy, improving stability and promoting application.
