从上海港可持续发展和长江三角洲、长江流域社会经济发展角度出发，提出并论证了依托横沙浅滩开发建设大型深水港区的技术可能性，通过潮流数值模拟分析了港区规划的初步形态，利用多种泥沙估算方法对港池和航道回淤强度进行了估算，研究认为，依托横沙浅滩开发建设大型深水港区技术上是可能、可行的。

In order to ensure the sustainable development of Shanghai Port and the economical and social development of Yangtze River Delta and Yangtze River Basin, this paper proposes and demonstrates the technological possibility of the port site on Hengsha shoal, analyzes the preliminary layout of the port by the numerical simulation model, and estimates the sedimentation intensity by means of various methods. The conclusion indicates that the port site of Hengsha shoal is possible and feasible.
