Based on the seismic damage data of Wenchuan earthquake, the seismic vulnerability model of entirety and different sections of mountainous tunnel is obtained by regression analysis. The peak ground acceleration (PGA) was selected as the ground motion parameter and the lognormal distribution was selected as the vulnerability model, and the seismic vulnerability curves of the tunnel structure of entirety and different sections (entrance shallow burial section, entrance transition section, ordinary section, fractured section) were obtained by the maximum likelihood estimation, and the vulnerability characteristics of different section and the whole tunnel were compared and analyzed. Under the condition of slight damage, the seismic vulnerability of the entrance shallow burial section is higher than that of other section. With the increase of the degree of damage, the seismic vulnerability of the fractured section is gradually higher than that of other sections of the tunnel. The average loss rate model of the tunnel was established by combining the loss ratio of tunnel structure in a specific failure state. The tunnel vulnerability models and average loss ratio model established in this paper can be used to evaluate the seismic loss rapidly in the event of similar earthquakes in the future.
