摘　　要：对于布置在岛礁附近的浮体,复杂海底地形的作用不可忽略。文章基于RMFC模型,同时将地形作为固定物体,研究了复杂海底地形对布置于岛礁附近的超大型浮体的运功响应和连接器载荷的影响。数值计算结果表明,地形的存在对浮体绕射力存在显著的影响,同时增加了低频区域的连接器载荷。The variable seabed effect becomes significant for the floating structures deployed near island and reefs. In this paper, the Rigid Module Flexible Connector（RMFC） model is adopted with the seabed treated as a fixed body to study the influence of uneven seabed on the motion response and connector loads of Very Large Floating Structure（VLFS） near island and reefs. The numerical results indicate that the uneven seabed has a significant influence on the diffraction force and the connector loads are enlarged in low wave frequencies.
