九圩港闸下新建桥梁工程，不能单独从泥沙问题来考虑其影响，还应考虑工程后对九圩港闸引、排水功能以及对闸上已有桥梁工程的影响。通过物理模型试验研究将较好地解决相关难题，为工程决策、设计提供科学依据。研究结果表明，桥梁工程方案实施后潮位最大壅高0.028 m，对流速影响较大的范围在桥轴线上下100 m之内，对九圩港闸引、排水流量的影响在3豫以内。
九圩港閘下新建橋樑工程，不能單獨從泥沙問題來攷慮其影響，還應攷慮工程後對九圩港閘引、排水功能以及對閘上已有橋樑工程的影響。通過物理模型試驗研究將較好地解決相關難題，為工程決策、設計提供科學依據。研究結果錶明，橋樑工程方案實施後潮位最大壅高0.028 m，對流速影響較大的範圍在橋軸線上下100 m之內，對九圩港閘引、排水流量的影響在3豫以內。

The study on the bridge construction downstream Jiuweigang barriers includes the sediment-related issues,and the effects on the barriers diversion and drainage,as well as the exiting upstream bridge construction after the project implementa-tion should be considered. The related problems will be solved by the present physical model, and the scientific basis will be provided for the project policy decision and design. The results show that, after the implement of the bridge beams scheme, the maximum back water is about 0.028 m;the major influence region is within the range of 100 m up and down the bridge ax-is;the later engineering influence on the diversion and drainage discharge is within 3%.
