Abstract: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 sh… Show more
