某核电工程海区水沙条件分析

为了从宏观上论证某拟建核电取水工程平面布局的合理性,依据大量实测资料,研究了该工程海区的水动力条件、泥沙环境以及岸滩冲淤演变特征。通过研究表明,该工程水域水动力不强、含沙量低、岸滩基本处于稳定状态,外界泥沙来源较少,在合理布置取水工程后不会产生较强的泥沙淤积问题。此外还结合该区的波浪及底质特点讨论了取水口位置,并进一步给出了局部防淤的相关措施。

Analysis on hydrology and sediment condition of a nuclear power plant project sea area

In order to demonstrate the rationality of the water intake project layout design of a nuclear power plant,the characteristics of hydrodynamic condition,sediment environment and coastal evolution were studied according to abundant survey data.The research indicates that the weak hydrodynamic force,low sediment concentration,stable seabed in long term and absent sediment source are advantages to the power plant intake.Therefore,the serious siltation will not occur in the intake of nuclear power plant with reasonable layout.Moreover,the location of intake was discussed considering the wave and seabed sediment,and some measures for preventing siltation were suggested.
