摘　　要：我国沿海发达地区尚未开发的天然建港岸线资源所剩不多,近年来在沿海可以利用的地区已建设或规划多个大型挖入式布局港池。挖入式布局的港池因具有充分利用岸线、掩护条件优越、便于管理等特点,在国内外应用较广。港池设计波要素是码头设计过程中的重要研究参数之一,而目前主流的商业软件MIKE 21 SW波浪模型、MIKE 21 BW波浪模型在对大范围港池的港内波浪场进行计算时各有欠缺。以横沙大型港池为例,比较几种不同波浪推算方法的计算结果,提出了结合MIKE 21 SW、MIKE 21 BW两种波浪模型进行叠加的推算方法。There are few natural harbor shoreline resources left in the developed coastal areas of China.In recent years,a number of large dig-in harbor basins have been constructed or planned in the areas that can be used in the coastal areas.Because of the advantages of making full use of the coastline,favorable cover conditions and easy management,dig-in harbor basin layouts are widely used in the world.The design wave element of basin is one of the important research parameters in the process of wharf design.At present,the mainstream commercial software MIKE 21 SW wave model and MIKE 21 BW wave model have their own shortcomings in calculating the wave field in basin with a wide range.Taking Hengsha large-scale harbor basin as an example,the calculation results of several different wave estimation methods are compared,and a method combining MIKE 21 SW and MIKE 21 BW wave models is proposed.
