In this paper, three dimensional numerical models for shield tunnel lining bolted joints, which are suitable for seismic excitation and static pressure of surrounding rocks, are established respectively. The influence of different seismic directions on the stress and deformation characteristics of bolted joints is studied in detail. Based on the existing tests, the numerical model of double segment bolted joint was verified. Then, the mechanical properties of the lining joint with different bolted forms were explored, and the applicability analysis of connecting bolted under seismic excitation and surrounding rock static pressure was improved. The results showed that: Compared with the deformation of the circumferential joint under the earthquake transverse excitation, the deformation of the circumferential joint under the longitudinal earthquake excitation is relatively more significant, and the deformation of the inclined bolted joint is the largest. Under the static pressure of surrounding rocks, the opening of the inclined bolted joint is the smallest, but the dislocation is the largest. The opening of the bent bolted joint is the largest, while the dislocation is the smallest. The stress value of the inclined bolted is the largest, whereas the stress value of the bending bolted is the lowest.
