Abstract: The strongly weathered mudstone is prone to collapse and collapse in the presence of water, and has the unfavorable characteristics of creep and long-term strength reduction.The tunnel from Jetta road to Automobile Park in Changchun Metro Line 2 project is mainly located in the strongly weathered mudstone, and the part near the car Park Station is located in the fully weathered mudstone.The time history analysis method is used in this paper.The three-dimensional calculation model of shield tunnel structure and surrounding soil layer is established, the dynamic characteristics of underground structure under earthquake load are simulated, and the displacement time-history response and deformation rule of interval under earthquake action are revealed.The conclusion of this paper can also be used as a reference for seismic performance analysis of shallow buried mine adit.
