摘　　要：以尼日利亚莱基港项目为依托,针对项目所处海域掩护条件和水深条件差、沿岸输砂冲淤明显,以及波浪周期长、波高大、波向集中的建港条件,围绕工程建设后对上下游岸滩的治理、平衡以及新建对泊稳要求较高的集装箱码头等核心问题,采用数值模拟、物模试验等研究方法,结合工程造价与工期进行技术经济比选,确定项目的总体布置思路、进港航道与防波堤走向、码头前沿线等总平面布置要点,形成科学、经济、合理的总平面布置方案,提出和总结了在强涌浪、强冲淤海域建设码头的总体平面布置的新思路及设计方案概要,为类似条件下的海港建设提供参考借鉴。This paper focuses on the project of LEKKI Port in Nigeria.In view of the poor shield and water depth conditions in the sea area where the project is located,obvious coastal flushing and silting,long wave period,high wave,and concentrated wave direction,this paper studies the core issues such as the management and balance of upstream and downstream beaches after the construction of the project and the construction of new container terminals with high requirements for berth stability.The paper uses the methods of numerical simulation and physical model tests to determine the general layout points such as the overall layout ideas of the project,the direction of the entrance channel and breakwater,and the location of the terminal front line.As a consequence,the general layout scheme is presented to be scientific,economic,and reasonable.This paper also proposes and summarizes a new idea and design scheme summary for the overall layout of wharf construction under strong wave surging and flushing conditions,which can be used as a reference for port construction in similar conditions.
