摘　　要：随着“一带一路”的建设,西非、地中海以及印度洋沿岸等海域由于其特定的自然条件导致具有明显的长周期波浪成分,且已对港口工程建设产生了严重影响。结合非洲某港口工程实例,其具有波浪周期长以及沿岸输沙量大两大特点;长周期波及大输沙量易引起港内泊稳条件差、泥沙淤积重,外海船舶施工风险大等问题,经对其平面布置方案研究后,决定采用挖入式港池布置方案,并通过波浪泥沙数学模型及物理模型试验等研究方法进行验证。结果表明,该挖入式港池方案能较好地解决以上问题。With the construction of “the Belt and Road”,the coastal areas of West Africa, Mediterranean and Indian Ocean have obvious long-period wave components due to their specific natural conditions, which have a serious impact on port engineering construction. The example of a port in Africa in this paper has the characteristics of long wave period and large coastal sediment discharge, and long period wave and large sediment discharge are easy to cause problems such as poor mooring stability conditions in the port, heavy sediment deposition, and high construction risks of offshore ships. After studying the general layout scheme, we decide to adopt the layout scheme of excavated-in harbor basin, and verify the scheme by the research methods of wave-sediment mathematical model and physical model test.The results show that the excavated-in harbor basin scheme can better solve the above problems.
