【摘要】：口门布置是港口规划中非常重要的环节。港口口门方位、口门位置、口门宽度、口门轴线方向的合理设计可以给船舶在港内操作提供比较平稳的水域。口门有效宽度对船舶进出港具有重要意义,它应根据港口近远期发展规模、进出港口的船舶数量、吨级及航行自然条件等因素确定。本文通过分析比较中外港口口门有效宽度设计标准,实际统计中外口门有效宽度使用情况,目的在于发现口门有效宽度的统计性规律,为我国港口口门有效宽度的实际运行标准提供参考依据。本文作者应用GOOGLE EARTH软件对全球范围内近500个不同类型港口的口门相关数据及卫星图中在港最大船长进行测量,并应用SPSS软件对数据进行了统计和分析,从而找出国内外在实际使用港口口门有效宽度的最小控制标准是有区别的结论,为我国突破口门有效宽度使用限制的标准提供了可能性。本文的数据分析结果表明,与外国港口相比,我国口门有效宽度实际操作控制标准是偏于保守的,存在着放宽的空间。论文根据国内外大量的实例,提出了口门有效宽度与最大船长比的控制建议值,为在现有条件下,大船进出小港、老港提供了操作的可能性。
[Abstract]:Gate layout is a very important link in port planning. The rational design of the axis of the entrance can provide a relatively stable water area for the operation of the ship in the port. The effective width of the port is of great significance to the entry and exit of the ship, and it should be based on the short-term and long-term development scale of the port. The number of ships entering and leaving the port, the tonnage and the natural conditions of navigation are determined. Through the analysis and comparison of the design standards of the effective widths of the ports at home and abroad, the actual use of the effective widths of the ports at home and abroad is counted. The aim of this paper is to find out the statistical law of the effective width of the port gate, and to provide a reference for the practical operation standard of the effective width of the port door in China. In this paper, the author uses GOOGLE EARTH software to measure the largest captain in Hong Kong in nearly 500 different types of ports in the world. The SPSS software is used to make statistics and analysis of the data, so as to find out the difference between the minimum control standard of effective width of port gate used at home and abroad. It provides the possibility for the standard of the effective width of the breakthrough door in our country. The results of data analysis in this paper show that, compared with foreign ports, the actual operational control standard of effective width of gate in China is conservative and there is room for relaxation. This paper is based on a large number of examples at home and abroad. The proposed control value of the effective width ratio of the gate to the maximum captain is put forward, which provides the possibility of operation for the large ship entering and leaving the small port under the existing conditions.
