| 英文摘要 | In terms of Biot's dynamic theory, the method of complex variable functions and multi-polar coordinates is used to solve the problem of the dynamic response to incident body waves of infinitely long cylindrical cavities in a porous medium half-space. Here, a circular arc with large radius is used to simulate the straight boundary of the porous medium half-space. By using the theory of Helmholtz, the equations of the steady-state Biot wave motion are decoupled to Helmholtz equations by introducing potential functions. Utilizing the general solution of the potential functions, expressions for the displacements, stresses and pore pressures within the porous medium, and expressions for the displacements and stresses at the boundary of the cylindrical cavities can be obtained for certain boundary conditions. Variations with different parameter conditions of the coefficients of dynamic stress concentration and pore water pressure concentration at the cavity boundary are discussed. A numerical example indicates that the method is useful and efficient in examining the dynamic response of cylindrical cavities in a porous medium half-space. |
