港口开发建设对田湾核电站取水工程的影响

建立了基于不规则三角形网格潮流泥沙数学模型,在对模型进行充分验证的基础上,对连云港港口扩建(旗台港区建设)规划方案和埒子口港区规划对田湾核电站已建取水工程的影响进行了数值模拟研究,计算了取水口附近滩面的冲淤变化和等深线位移。研究结果表明:连云港港口扩建及埒子口港区规划实施后,已建的田湾核电站取水明渠口门附近水域变成泥沙淤积环境,滩面将会淤高,设计的取水口门水深等深线将会外移,核电站正常取水将会受到影响。

Numerical modeling of tidal current and sediment movement in coastal area near Tianwan Nuclear Power Statiom

Mathematical models of tidal current, sediment movement and seabed erosion and deposition are set up with irregular triangular grids. On the basis of full validation and verification of the models, the impacts of the extension project plan(Qitai harbour construction plan)of Lianyungang Port and Liezikou harbor on the constructed water intake project of Tianwan Nuclear Power Station are numerically studied, and the seabed erosion and disposition near the water intake and the displacement of the water intake isobath are calculated. The study results show that the coastal waters near the water intake will become a sediment deposit-promoting environment, the seabed will rise and the isobath at water intake will move outward after the construction of Lianyungang Port's extension project and Liezikou harbor project, and the water intake of Tianwan Nuclear Power Station will not be able to work regularly.
