Fault, crushed zone, and other unfavorable geology may frequently appear in the construction of tunnels, so it is of course necessary to study on the dynamic properties of tunnels crossing rock fracture zone. Taking the tunnel crossing faults as the object, this paper discussed the dynamic constitutive relation satisfied by tunnel structures and researched the loading features and failure characteristics of the different tunnel crossing faults. It shows that: (1) tunnels in areas with high seismic intensity shall have reinforced concrete lining, to improve its ability of resisting tension failure, (2) the stress at the waist on both sides of the tunnel arch is the maximum, and tunnels in areas with high seismic intensity shall have reinforced concrete lining to improve its ability of resisting tension failure. This research is of great reference significance to the construction of tunnels crossing rock fracture zone.
