周公堤水道张家湾透水坝平面布置及结构形式比较分析

为了不影响周公堤水道颜家台闸的正常使用,已建的周天河段航道整治控导工程在颜家台一带方案布置存在空档,使得河道局部放宽,泥沙落淤,形成浅埂。因此,在长江中游荆江河段航道整治工程昌门溪—熊家洲段工程(周天河段)中,在空档处布置了一道潜丁坝。为了在增加工程效果与减小对颜家台闸的影响之间找到平衡点,对张家湾透水坝的平面布置及结构形式进行研究,为该工程的顺利实施提供支撑。

Comparative analysis of layout and structure of filter dam at Zhangjiawan of Zhougongdi waterway

In order to guarantee the normal operation of Yanjiatai sluice gate, a gap exists in the layout scheme of the waterway regulation project of Zhoutian river. Due to the broadened local waterway, sediment deposits to form shallow ridges. A filter dam will be constructed in Zhoutian river (between Changmenxi and Xiongjiazhou of the waterway regulation project of Jingjiang, the Yangtze River) to reduce sediment deposition and minimize relevant effects on Yanjiatai sluice gate. The research focuses on the layout and structure type design, and provides a theoretical basis for the successful implementation of this project.
