Study of Non-uniform Seismic Response of Intercity Tunnels with Defective Shields

Based on the structural viscoelastic boundary theory, considering geological changes of soil layer and depth tunnel crossing, dynamic time course analysis is carried out for defective lined tube sheet structure under non-uniform seismic excitation, to obtain force deformation law whole as well section. Analyze response shield non-consistent excitation influence misalignment factors, summarize intrinsic mechanism lining structure, identify phenomena affecting junction damage, refine safety evaluation method structure.
