| 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。

| 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 mode1.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. |
