| 摘 要： | 掌握核电站周边海域流场特征对保障核电冷源安全及研究排水口温排水输运规律具有重要意义。基于2013年12月~2014年2月在红沿河核电站邻近海域获取的四个站点海流连续观测资料,利用低通滤波和调和分析的方法,分析了该海域的余流和潮流特征。结果表明,核电站邻近海域冬季余流流速大于秋季,且随深度增加而减小;中层附近余流变化较小,越接近底层余流变化越大;海域潮流类型属于规则半日潮流,且浅水分潮特征显著; M_2和K_1分潮流的最大流速随深度增加而减小;除取水口站位外,其他站位主要分潮流运动形式皆表现为往复流特征。

| Abstract: | It is of great significance to master the characteristics of the current fields around the nuclear power station, for ensuring the safety of nuclear cold sources, and for studying the transport of thermal discharge of water outlet. In this paper, based on the continuous current data of four sites near the Hongyanhe nuclear power station from December 2013 to February 2014, the characteristics of residual and tidal current were analyzed by means of low pass filtering and harmonic analysis. The results showed that the velocity of the residual current was stronger in winter than that in autumn, and decreased with depth. In the middle layer, the velocity variation of residual current was smaller than that in the bottom layer. The tidal current in this sea area was a regular semi-diurnal one with the obvious shallow water effect. The maximum tidal current velocities of M2 and K1 components decreased with depth. Except for the site near the water intake, the motion types of the principal tidal current constituents in other sites were rectilinear. |
