摘要：

This paper studied the scattering of plane P waves by underwater saturated sand with a circular shield tunnel. The Biot dynamic theory and the Fourier-Bessel series expansion method are used to solve this problem. The complicated ground model is analyzed. The seismic response of tunnel structure-underwater stratum-water system is studied on the basis of the analytical solution. The influence that water depth and buried depth of tunnel put on the seismic response of tunnel lining and saturated sand is given. The analytical results indicate that the water depth has an unobvious influence on the seismic response of the tunnel lining and underwater saturated sand, while the buried depth of tunnel has an obvious influence on the seismic response of the complicated field, and the tunnel has an influence on the field only in a limited range.
