黄骅港综合港区深水航道水动力数值模拟研究

Hydrodynamic numerical simulation study on the deepwater channel of Huanghua port

采用数值模拟方法对黄骅港综合港区20万t级航道工程潮流动力进行研究,分析工程实施后最大流速、最大横流等,以掌握工程实施对周围海域的影响。研究结果表明:(1)方案的实施未改变大范围海域潮流运动规律,变化发生在工程附近海域;(2)综合港区深水航道内流速在-6 m口门附近出现最大值,为垂向平均0.86 m/s、表层0.92 m/s;整个航道内的流速值介于0.25~0.86 m/s之间(垂向平均);航道内最大横流位于航道向北转折段,另外-6 m口门附近横流也较大。

The numerical simulation method was used to study the tidal power of the 20,000-ton channel engineering in Huanghua Port,the maximum flow rate and the maximum cross flow after the implementation of the project were analyzed to master the impact of the project implementation on the surrounding sea.The study shows that：（1） Implementation of the scheme did not change the trend of the large-scale ocean currents,and the changes occurred in adjacent waters of the project;（2） After the upgrade of the waterway,the maximum velocity near the entrance of -6 m is 0.92 m/s,the vertical average is 0.86 m/s,and the maximum velocity（vertical average）within the channel is between 0.25~0.86 m/s,the maximum transverse flow in the channel is located in the northward turning section of the channel,also,there is a large cross flow near the gate of the-6 m.
