桃花港段长江岸线综合整治工程位于长江下游江阴水道进口段南岸，岸线建有大量的石油、化工码头。此段水面开阔，滩地芦苇丛生，岸线呈内凹的平面形态，泥沙易于落淤，不利于码头前沿水深及河势稳定。采用潮汐河工模型试验与二维水流潮汐数学模型计算相结合的方法，研究3个不同岸线整治工程方案对河段河势的影响。通过研究认为：不同方案工程兴建后，对工程上下游河段水位、河道主流区流速场及禄安洲分流比影响均较小。工程局部区域的流态发生了明显的变化，原滩地范围内的回流消失，工程外侧水流趋于平顺。从综合整治效果来看，推荐方案（方案3）增加了码头前沿及后方的疏浚工程，既能满足岸线平顺的需要，也能满足该段深水岸线开发利用需求，对地方社会经济发展更加有利。

The TaohuaPort section regulation project of the Yangtze River is located in the lower Yangtze river , south bank of the Jiangyin channel inlet section . Along with a lot of oil and chemical wharfs , this section is Open water and fully -grow with reeds . The coastline is a concave shape , and the sediment is prone to deposition , which is not conducive to the stability of wharf apron and river regime . Combining with tidal river model test and two -dimensional mathematical model of tidal currents method , three different regulation projects for the influence of river regime are researched in the article . Through research that different scheme of engineering construction has little influence on the water level and flow field of upstream and downstream , and the split ratio of Luan Island is stability . The flow patterns which near the engineering areas has changed significantly , the recirculation of the original beach disappeared , the outer mainstream tends to straight . Comprehensive comparation from the regulation effect , recommended program (Option III ) increased the dredging engineering which near the the wharfs , to meet both the needs of smooth coastline and improve deepwater coastline development , which bring more favorable to the utilization of local social and economic development .
