Abstract (English): The inner section of the outer channel of the 300 000 DWT channel at Lianyungang Port is the deep-water channel excavated on the shoal of the rotational flow sea area. The three-dimensional characteristics of the flow field in the channel near the port entrance, especially during the spring tide, are significant, and the navigation flow conditions are bad. Due to the lack of a fast and accurate way to obtain the navigation flow conditions during the tide riding period, in order to ensure the safe navigation of the ships entering the port, the 300 000 DWT bulk carrier is basically arranged to enter the port during the middle tide and neap tide with small flow velocity. In this paper, a three -dimensional tidal current numerical model was used to calculate and analyze the three-dimensional flow field characteristics of Lianyungang sea area under typical spring tide, as well as the flow field and cross-flow characteristics of the inner section of the outer channel of Lianyungang Port area during the tidal period. Based on the simulation results of the flow field of all the spring tides in 2025, the tidal current forecast table of the whole channel and all the tidal periods of the spring tides in 2025 was compiled, which is of great significance for the navigation and manipulation of ships during the spring tide period.

Abstract (Chinese): 连云港港区 30 万吨级航道外航道内段的口门区流场, 特别是大潮流场的三维特征显著, 通航水流条件较 差。由于目前缺乏快速、准确获取大潮乘潮时段通航水流条件的途径, 30 万吨级散货船基本在流速较小的中潮、小 潮时段进港以保证安全航行。文中采用三维潮流数模计算分析了典型大潮下连云港海域的三维流场特征, 以及连云 港港区外航道内段乘潮时段的流场和横流特征, 并基于 2025 年所有大潮的流场模拟结果编制了航道全线和 2025 年 度所有大潮乘潮时段的航道内潮流预报表, 对于大潮期船舶通航操纵具有重要意义. [ABSTRACT FROM AUTHOR]
