台山核电厂重要厂用水系统纳潮取水口潮流及泥沙研究

文章研究了台山核电厂重要厂用水系统纳潮取水工程。根据实测资料分析了自然条件和岸滩演变。分别建立了工程海区二维波浪、潮流、泥沙数学模型,并根据实测资料对夏季和冬季全潮水文进行了验证。在经验证的数学模型基础上,研究了重要厂用水系统纳潮取水工程实施后的潮流变化及泥沙回淤情况。结果表明,重要厂用水系统纳潮取水工程实施后,流场变化仅局限于安全取水工程附近小范围海域,进水前池附近水域泥沙年冲淤和骤淤都不大。因此,从潮流、泥沙角度考虑,重要厂用水系统纳潮取水工程是可行的。

Study on tidal current and sediment for water intake project of safety-related water service system of Taishan Nuclear Power Station

In this paper,the water intake project of safety-related water service system of Taishan Nuclear Power Station was researched.Based on the measured data,the natural conditions and coastal evolution were analyzed.A mathematical model of tidal flow and sediment was established in the sea area.Then the validation and verification of the model by summer and winter hydrological data were carried out.On this basis,the change of tidal current and sediment siltation after the water intake project implementation were studied.The results show that the change of flow field is limited in the sea area near the project.The annual siltation and the sudden siltation is little.Therefore,the water intake project of safety-related water service system is feasible from the perspective of tidal current and sediment.
