在Boussinesq方程和朗肯源法的基础上，建立了分析岛礁附近浮体水弹性响应的直接耦合方法。完成了详细的理论推导、数值求解方法和相应的计算程序THAFTS-BR。以均匀水深下的单模块超大型浮体为研究对象，通过比较常用软件THAFTS计算的浮体的水弹性响应，验证了THAFTS-BR程序的准确性和可靠性。最后，基于模型试验和数值方法对部署在岛礁附近的超大型浮体的运动和载荷进行了研究。得出了一些有益的结论，可为近岸、海岛浮体的动力响应分析、设计和施工提供参考。
A direct coupled method is established on the basis of the Boussinesq equations and RANKINE source method to analyze the hydroelastic responses of floating bodies near islands and reefs. The detailed theoretical derivation, numerical solution method and the relevant calculation program THAFTS-BR are also completed. A single module VLFS in uniform water depth is then taken as the research object, the accuracy and reliability of the THAFTS-BR program are validated by comparing the hydroelastic responses of VLFS calculated by the popularly-used software THAFTS. Finally, the motions and loads of the VLFS deployed near islands and reefs are investigated based on the model tests and the numerical method. Some useful conclusions are obtained, which can provide a reference for the analysis of dynamic responses, design and construction of the floating bodies near seashores and islands.
