摘　　要：MIKE21MA软件是一种全时域系泊分析软件,可以得出时域内各种复杂情况下的系泊船舶运动量和系缆力。文中介绍了MIKE21MA软件的基本理论,并以某码头项目为例,通过后报波浪要素分析,得出工程区周期、波高的分布规律,再利用MIKE21MA软件系统分析长周期波浪作用下周期、波高对船舶系泊稳定的影响。通过算例,得出波高保持不变的情况下,缆绳受力及船舶运动量随着波浪周期的增加而增加;在波浪周期不变的情况下,缆绳受力及船舶运动量随入射波高的增加而增加。MIKE21MA is a full time domain analysis software,which can obtain the motion and mooring force of mooring vessel under various complex conditions in time domain.In this paper,the basic theory of MIKE21MA was introduced.Taking a wharf project as an example,the distribution law of period and wave height in this project area was obtained through the analysis of hindcast wave elements.Then the MIKE21MA system was used to analyzed the influence of period and wave height on vessel mooring stability under the action of long period wave.The results show that when the wave height remains the same,the force on the cable and the amount of vessel movement increase with the increase of the wave period;when the wave period remains the same,the force on the cable and the amount of vessel movement increase with the increase of the incident wave height.
