长江口南槽航道透水梯形结构整治建筑物水动力特性研究

Study on hydrodynamic characteristics of permeable trapezoid structure of waterway regulation in the south passage of the Yangtze estuary

文章依托长江口南槽航道治理工程,对一种透水梯形结构整治建筑物进行了研究,通过物理模型试验重点研究了其水流流速和泥沙淤积效果等水动力特性,并根据试验结果对结构进行了优化。优化方案对透水梯形结构的不同开孔结构和底板方案进行了比选,基于比选试验结果,给出了推荐方案结构,可为生态航道建设提供参考。

In this paper,according to the project of the south passage waterway regulation in the Yangtze Estuary,the permeable trapezoid structure of waterway regulation was studied.By conducting the physical model tests,the hydrodynamic characteristics of current velocity and sediment siltation of the permeable structure were studied,and the structure was optimized based on the test results.For the optimization plan,different plans of different hole types and bottom types were compared,and the recommendation plan was proposed based on the comparison results.The study results can be referred to by other similar projects.
