中文摘要：

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。

英文摘要：

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.
