With the acceleration of urbanization in China, large-scale tunnel engineering has developed rapidly. The anti-seismic problem of tunnel engineering has become a research hotspot in the field of geotechnical seismic engineering. In this paper, the basic solution method of the orifice problem in the elastic theory is used to solve the internal force of the tunnel earthquake. The results show that the internal force of the tunnel structure is distributed along the circular tunnel in the shape of a goose egg. The larger the peak acceleration of the input seismic wave, the stronger the internal force of the tunnel structure. The conclusion provides a basis for anti-seismic design calculation of shield tunnel.
