摘　　要：介绍了流固耦合的基本理论和算法,包括流固耦合问题的基本概念与耦合机理的分类,探讨了强耦合和弱耦合算法的计算流程与适用范围,阐述了任意拉格朗日欧拉法、无网格法、特征线分离算法及基于流动条件插值的有限元法等流固耦合分析方法.述评了近年来流固耦合理论在土木工程领域的应用发展,并对流固耦合理论的研究与应用进行了展望.A systematic introduction about the basic theory of FSI（Fluid-Structure Interaction）,including basic concept and classification by interaction mechanism was first provided.Strong coupling method and weak coupling method were discussed and studied on the computation procedure and conditions.Then some successful analysis methods and progress for FSI such as ALE（Arbitrary Lagrangian-Eulerian） method,Meshless method,CBS（characteristic-based-split） finite element method and FCBI（flow-condition-based interpolation） finite element method were briefly described.The application and development of FSI theories in the domestic and abroad civil engineering areas were discussed in details.Research prospect on the FSI theory and its application was finally presented.
