A total of 81 mountain tunnels that were damaged in 10 strong earthquakes are studied. They are classified into six typical damage characteristics: lining cracks, shear failure of lining, tunnel collapse caused by slope failure, portal cracking, leaking, and deformation of sidewall/invert damage. Further study and discussion are carried out on influencing factors for mountain tunnels, including seismic parameters, structural information, and rock conditions. Suggestions are also made regarding seismic resistance and reduction.
