Many highway tunnels were subjected to varying degrees of damage in the 5.12 earthquake. According to the damaged features of tunnels in earthquakes at home and abroad, the macroscopic damage of tunnels are summarized. On the base of the damage manifestation, the failure mechanism of tunnel damage is preliminarily analyzed. Comparison with the failure mode on the shaking table model test has been made, and some suggestion of paying more attentions on the weak links at the tunnel entrance, faults and shallow buried section for designers has been put forward. |
