| 摘 要： | 为分析研究开敞水域中，水流斜跨航道进入航槽后的水流特征，垂直连云港外航道布置水文测量断面进行现场观测。通过观测分析，总结了槽中流速的垂向分布规律，以及流向对槽中流速的影响，并给出了槽中流速与边滩来流流速间的经验关系式。研究成果能为开敞水域航槽选线和回淤研究提供科学参考。

| Abstract: | In order to analyze the character of current when the flow crosses the navigation channel in open wide water,the field observation for the cross-section by hydrographic survey,which was perpendicular to the outer waterway of Lianyungang port,was carried out.Through the analysis,the vertical velocity distribution and the influence of the flow direction when the flow crosses the navigation channel were summarized.Meanwhile,the empirical formula for computing the flow velocity in the channel is analyzed.The re... |
