Abstract The paper conducts the research on the force-deformation mechanism under the effects of stick-slip dislocation of the normal fault with 75° obliquity by making use of 1∶50 model experiment. And the strata pressure of the tunnel vault and bottom，axial strain and hoop strain are monitored. Result shows that with the normal fault rupture propagating in the overburden layer，the tunnel structure which is orthogonal to the normal fault will undergo relatively big shear displacement. The strata permanent deformation and the interaction between the strata and the tunnel structure causes the formation pressure changes significantly，of which the pressure on the vault in the hanging wall zone increases significantly，followed by the pressure on the vault in the foot wall zone. The pressure on the tunnel bottom in the hanging wall zone decreases，while greatly increases in the foot wall zone. That leads the tunnel being possibly separated from the wall rock so as to accommodate the shear displacement of the fault. The longitudinal bending moment in the hanging wall zone is positive and negative in the foot wall zone. By judging the lining failure from the cement prototype under compression，the maximum allowed fault displacement of the prototype structure D = 1.25 m is determined. Theoretically，the value is overestimated.
