| 摘 要： | 整治线型对航道整治工程设计施工的意义重大,以往多根据经验确定。考虑到环流消失对弯道过渡段水流挟沙力减小、泥沙淤积、浅滩碍航的影响,以弯道环流运动研究成果为基础,分析不同环流消失长度公式,选取张定邦公式进行改进,初步探讨了整治线型确定的理论公式法,并采用长江中游弯道河段实测数据对公式进行了验证。

| Abstract: | The regulation line type is an important parameter to waterway regulation work,but there is no better method to design it except working according to experience.Considering the influence of circumfluence disappear and on sediment-carrying capacity at the transition section of the bents,siltation,and shoal's navigation-obstruction,we analyze various formulae concerning circumfluence disappearing length,and discuss to establish a regulation line formula to decide the length of the transitional reach by introduce the circumfluence disappearing theory.And it is well used on the middle reach of the Yangtze River. |

| Keywords: | regulation line type regulation line circumfluence circumfluence disappearing |
