摘要: 铜鼓滩为长江上游枯期重点维护的卵石浅险滩。通过实测资料分析和平面二维数值模型计算,阐述了滩段的碍航成因,研究表明左槽方案水流条件较好,但对河势的改变相对较大,新开航槽的稳定性较差;右槽整治方案工程投资少、对河势的影响相对较小,基本满足航道要求,选择右槽整治推荐方案。

关键词: 航道整治, 二维数值模型, 水流条件

Abstract: Based on the analysis of basic characteristics of Tonggutan Reach in the Yangtze River, variations of the navigable conditions caused by the regulation project are investigated by 2-D mathematical model.The results show that the navigable conditions in the reach after implementation of the regulation project can basically meet the standards, but the branch will be with low stability.

Key words: waterway regulation, 2-D mathematical model, flow condition
