The coupling of finite element method and finite element method is used to discuss the seismic response of traffic tunnel under seismic wave and to consider the nonlinearity and stratification of the soil.Neutralmark-β is used to solve the dynamic equilibrium equation by using the equivalent linear model to deal with the soil nonlinearity. Through the example calculation, the response of the initial structure under earthquake is given
