Abstract Considering the fluid-soil coupling of saturated soil and seawater-saturated soil-structure dynamic interaction, the Hankel function integral transformation method is employed herein to obtain an analytical solution to the scattering and diffraction problem posed by the plane SV-waves in an undersea lined tunnel. This study is based on the porous medium wave function theory of saturated soil proposed by Biot and the ideal fluid medium wave theory. The impact of factors, such as the incident angle, frequency, water depth, buried depth of tunnel, porosity, and Poisson's ratio of the saturated soil, on the horizontal and vertical displacement at the seawater–saturated soil interface, and on the pore water pressure and total circumferential stress at the saturated soil–tunnel interface, are computed and analyzed.
Highlights Analytical solution to scattering of plane SV waves by a circular lined tunnel in an undersea saturated half-space is obtained. The Hankel function integral transformation method is employed herein. The effects of water depth, saturated soil parameters and wave characters on the seismic responses of the tunnel and undersea layer are analyzed.
