摘　　要：针对黑沙洲水道分汊多、流量大且长江下游感潮河段水流复杂的综合特点,对水文观测资料进行分析和总结。结合航道整治二期工程建设的现场实践工作,对水文观测中的表面流速流向测量、比降观测、水文断面测量等进行深入研究,依托现代新设备和新技术,优化布设水文断面和水尺位置,高效组织实施,提高工作效能,获取完整详实的水文观测数据。该方法有效解决了长江下游感潮河段水文观测中存在的问题,为工程设计、施工及相关专题研究提供了可靠的基础资料。研究成果可为类似工程提供借鉴。In response to the comprehensive characteristics of multiple branching and large flow of the Heishazhou waterway,as well as the complex flow of the tidal river section in the lower reaches of the Yangtze River,the hydrological observation data are analyzed and summarized.Combined with the on-site practical work of the second phase of waterway regulation project construction,in-depth research is conducted on surface velocity and flow direction measurement,gradient observation,hydrological section measurement,etc.in hydrological observation.Modern new equipment and technology are used to optimize the layout of hydrological sections and water gauge positions,efficiently organize and implement,improve work efficiency,and obtain complete and detailed hydrological observation data.This method effectively solves the problems existing in the hydrological observation of the tidal reach of the lower reaches of the Yangtze River,and provides reliable basic data for the project design,construction and related thematic research.The research results can provide reference for similar projects.
