On the basis of Biot dynamic theory for saturated, porous, elastic media, analytical solutions are presented for two-dimensional scattering and diffraction of transient plane SH waves by deep-buried, cylindrical, lined cavity in saturated porous elastic soil employing the Laplace transform and wave function expansion method according to the continuous conditions on saturated soil and lining structure interface and the stress-free condition on the surface of lining structure. The solutions can be degenerated under the condition of deep-buried, cylindrical cavity or rigid inclusion in saturated, porous, elastic soil or in the elastic medium. The solutions also are proofed by being compared with the existing related solutions. Numerical results are given, the effect of the lining thickness and stiffness on the stress concentration factor of the outside boundary of lining is shown.
