Abstract: Objective During construction, super-large diameter shield tunnels are subjected to multiple forces which may easily cause structural damage and waste leakage. To ensure the safety of the segmental lining structure, it is necessary to study its mechanical response characteristics under the coupled action of various construction loads. Method Based on an actual super-large diameter shield tunnel project, the numerical simulation method is adopted, and a three-dimensional numerical model for super-large diameter shield tunnel consisting of 22 segmental rings and connecting bolts is established using ABAQUS software. The accuracy and feasibility of the model are validated by a comparison with experimental results of the same type. The effects of tunnel burial depth and shield posture are fully considered in the 3D numerical model calculation, the stress and deformation characteristics of lining segments and bolts at different positions are analyzed. Result ＆ Conclusion The influence range of jacking thrust on the lining segments mainly covers the first eight rings, while its effect on the bolts is primarily concentrated in the first four rings. Under different shield tunneling postures, the stress state of segments on the same side shows more significant changes. The stress and deformation of segments are highly sensitive to tunnel burial depth but relatively less affected by shield postures. As burial depth increases, the displacement at lining arch vault decreases, while the displacements at arch waist and arch invert tend to increase overall. When construction errors are not considered, the influence of burial depth on the stress of circumferential bolts is minimal. Since the locations of maximum bolt stress generally concentrate at arch waist, it is recommended to pay special attention to the stress state of bolts and the potential damage to bolt holes and hand holes at lining arch waist.
