东非某港改扩建工程狭窄港池布置特点

Layout characteristic of narrow harbor basin for port expansion project in East Africa

以东非某港改扩建工程为例,阐述狭窄港池中水域平面尺度的设计方法,包括兼顾航行通道功能的港池宽度、回旋水域直径、口门宽度等。对国内外相关规范关于水域平面尺度的计算方法进行对比研究,结合经验确定水域平面尺度的初步设计方案,并开展船舶操纵模拟试验对设计方案的合理性进行验证。结果表明,本工程的水域尺度布置合理,能够满足船舶通航及靠离泊要求,并有效减少疏浚量、控制工程投资。

Taking the expansion project of a port in East Africa as an example,we elaborate the design method of water area dimensions in the narrow harbor,including basin width with the navigational channel function,turning basin diameter,and entrance width.We conduct a comparative study on domestic and foreign standards regarding the calculation methods of water area dimensions,determine the preliminary design scheme for water area plan dimensions based on the experience,and carry out a ship maneuvering simulation test to verify the rationality of the design scheme.The results show that the water area layout of this project is reasonable,which can meet the requirement of ship navigation,and effectively reduce dredging volume and control engineering investment.
