摘　　要：从水体的研究角度出发,介绍有限差分法、有限体积法、有限元法、边界元法等分析方法以及Lagrange坐标系、Euler坐标系和ALE等描述方式在坝库系统相互作用中的选取与应用。通过对比分析可知:各种方式都有优点及局限性,应具体问题具体分析;ALE描述方式具有其独特优势,被较多应用在流固耦合分析领域。最后指出,对于流固耦合问题,需要在数学模型、接触边界相容条件的处理等方面进行深入研究。The selection and application of analysis methods used in water research, such as the finite difference method （FDM）, finite volume method （FVM）, finite element method （FEM）, and boundary element method （BEM）, and methods of description such as the Lagrange coordinate system, Euler coordinate system, and arbitrary/_agrangian-Eulerian （ALE） system, which are applied in dam-reservoir interaction research, are introduced. Through comparison and analysis, it is found that any method has advantages and hmitations, and it must be capable of analyzing concrete conditions. Because of its unique advantages, the ALE description method has been more often nsed in the field of fluid-sohd coupling. Finally, it is pointed out that further study should be conducted on the mathematical model, the contact boundary conditions, and so on.
