| 摘 要： | 本文应用解析法和有限单元法研究了流体－固体介质中平面瑞利波波速度弥散性及位移分布规律．利用有限单元法推导了液体介质中平面瑞利汉传播的单元刚度矩阵和质量矩阵，以及利用解析法获得了半无限层提供的边界力．结合文献（１）给出的固体介质中有限单元刚度矩阵和质量矩阵，本文得到了流体－固体介质中瑞利弥散特征方程和位移计算公式．

| Abstract: | The veilocity dispersion characteristics and dilplacement distribution of plane Rayleigh wave in fluid--solid media are studied by using finite element method and analytical method in this paper. The elemept stiffness matrix and mass matrix of plane Rayleigh wave propagation are calculated using finite element method in fluid-solid media. The boundary forces provided from semi-infinite layer are calculated using analytical method. Conbining finite element stiffness matrix with mass matrix in solid media, the authors presents a Rayleigh wave secular equation and displacement formulation in fluid-solid media. |
